HLV Series Tube Heater

Vacuum System

Design, Installation, Operation, and Maintenance Manual

The HLV Series Infrared Tube Heater is a negative pressure, two stage radiant heater vacuum system designed to provide comfort heat. Consisting of four main components (a burner control box, radiant tubes, reflector assembly, and vacuum exhauster), this system generates infrared energy to heat the objects in the space. These objects then reradiate this heat, creating a comfort zone at the floor level.

This allows large spaces to be heated efficiently without having to provide primary infrared for every square foot of space.

!

WARNING

Improper installation, adjustment, alteration, service, or maintenance can cause property damage, injury, or death. Read the installation, operation, and maintenance instructions thoroughly before installing or servicing this equipment.

This heater must be installed and serviced by trained gas installation and service personnel only. Failure to comply could result in personal injury, asphyxiation, death, fire, or property damage.

In locations used for the storage of combustible materials, signs must be posted to specify the maximum permissible stacking height to maintain the required clearances from the heater to the combustibles. Signs must either be posted adjacent to the heater thermostats or, in the absence of such thermostats, in a conspicuous location.

For Your Safety

Not for residential use!

Do not use this heater in the home, sleeping quarters, attached garages, etc. Installation of a commercial tube heater system in residential indoor spaces may result in property damage, serious injury, asphyxiation, or death.

Clearances to Combustibles

!

WARNING

Failure to maintain minimum clearances to combustibles may result in fire and/or explosion, property damage, serious injury, or death. Always maintain minimum clearances and post clearance safety limit signs or the clearance safety tag where needed.

Clearances to combustibles is defined as the minimum distance that must exist between the tube surface, or reflector, and any combustible items (see Figure 1.2). It also pertains to the distance that must be maintained from moving objects around the tube heater. Moving items include, but are not limited to, vehicle lifts, overhead doors, cranes, and hoists. For instance, if vehicle lifts are present, ensure that clearances will be maintained from the highest raised vehicle.

If you are unsure of the potential hazards in the application, consult your local fire marshal, insurance carrier, or other qualified authorities on the installation and approval of the proposed installation.

!

WARNING

Placement of explosive objects, flammable objects, liquids, and vapors close to the heater may result in explosion, fire, property damage, serious injury, or death. Do not store or use explosive objects, liquids, or vapor in the vicinity of the heater.

Clearances listed in Chart 1.2 on page 9 apply to each individual burner in the HLV system. When installing the tube heater vacuum system, clearances to combustibles for each burner model and its applicable tube run must be maintained. Inspect each burner rating label to ensure that clearances are maintained.

In locations used for the storage of combustible materials, signs must be posted to specify the maximum permissible stacking height to maintain the required clearances from the heater to combustibles. Signs must be posted adjacent to the heater’s thermostat or, in the absence of such thermostat, in a conspicuous location.

The stated clearances to combustibles represents a surface temperature of 90°F (50°C) above room temperature. Building materials with a low heat tolerance (i.e. plastics, vinyl siding, canvas, tri-ply, etc.) may be subject to degradation at lower temperatures. It is the installer’s responsibility to ensure that adjacent materials are protected from degradation.

Design

Pre-Design for Non-Condensing and Condensing Systems

The HLV Series vacuum system can be designed as a non-condensing or a condensing system .

After reviewing the following pre-design guidelines, proceed to the appropriate section for the desired system. If uncertain as to what type of system should be used, begin by designing for a condensing system (see page 12). If the completed design does not require condensing pipe then, by default, the system will become a non-condensing system. Refer to page 11.

1 Most non-condensing systems should be controlled via a single temperature zone. If two zones are required, it will be necessary in most cases to design the system as a condensing system

(see page 12). Contact the factory for additional guidelines.

2 Determine the heat load requirement of the building.

3 Available mounting heights and coverage are the two most critical variables in input (BTU/h) selection and quantity.

• The mounting height of the system determines the largest burner model that can be used.

• When the design is calculated, if it is discovered that the quantity of burners in the system will not provide sufficient coverage, it may be necessary to use a larger quantity of lower input burners, sometimes resulting in the need for additional vacuum pumps.

4 When determining system location, clearances to combustibles must be maintained. Items such as lights, sprinkler heads, overhead doors, storage areas containing stacked materials, gas and electrical lines, parked vehicles, cranes, and any other possible hazards must be taken into account. Refer to Chart 1.2 on page 9 for Clearances to Combustibles distances.

IMPORTANT : Fire sprinkler heads must be located at an appropriate distance from the heater.

This distance may exceed the published clearances to combustibles as posted on the heater.

Certain applications may require the use of high temperature sprinkler heads or relocation of the heaters.

Sprinkler systems containing propylene glycol or other potentially flammable substances are not to be used in conjunction with this heater without careful consideration for, and avoidance of, potential fire or explosion hazards. For further information consult NFPA 13.

Design • Design for Non-Condensing Systems

Design for Non-Condensing Systems

System tube lengths are determined by the gas input (BTU/h) of each burner. Chart 2.1 below indicates system design parameters for each burner model used in each system. When calculating tube lengths, do not add in elbow and tee fittings as they have been accounted for.

Designing a non-condensing system can be fairly straightforward given the below steps are followed carefully. In addition to these steps, an understanding of design definitions is critical.

Refer to page 14 for these terms and illustrations.

1 Begin by designing a tentative layout without regard to design parameters. Use this approach to place each burner and the vacuum pump where most desired (refer to Figures 2.4 - 2.10 for typical layouts).

2 Once a tentative layout has been established, confirm that each run in the system meets the criteria for ‘Calculated Minimum Run.’ ‘Calculated Minimum Run’ is determined by adding the total ‘Single Flow’ plus one-half of the ‘Common Flow.’

• If the system does not meet the ‘Calculated Minimum Run’, length must be added to the run until all burners meet the design parameters.

• If the run exceeds the ‘Calculated Maximum Run,’ it will be necessary to either make the system a condensing system or shorten the runs which exceed this criteria.

3 Confirm the following applies (non-condensing systems only): a) A maximum of two elbows per run is allowed per system.

b) A maximum of three intersections (tees or crosses) are allowed per system.

c) All elbows and intersections less than 20 feet from a burner require a reflector.

Design for Condensing Systems

System tube lengths are determined by the gas input (BTU/h) of each burner. Chart 2.2 below indicates system design parameters for each burner model used in each system. When calculating tube lengths, do not add in elbow and tee fittings as they have been accounted for.

Designing a condensing system can be fairly straightforward given the below steps are followed carefully. In addition to these steps, an understanding of design definitions is critical. Refer to page 14 for these terms and illustrations.

1 Begin by designing a tentative layout without regard to design parameters. Use this approach to place each burner and the vacuum pump where most desired (refer to Figures 2.4 - 2.10 for typical system layouts).

2 Once a tentative layout has been established, confirm that each run in the system meets the criteria for ‘Calculated Minimum Run.’ ‘Calculated Minimum Run’ is determined by adding the total ‘Single Flow’ plus one-half of the ‘Common Flow.’

• If the system does not meet the ‘Calculated Minimum Run,’ length must be added to the run until all burners meet the design parameters.

3 Refer to Chart 2.2 to determine the ‘Calculated Starting Point of Condensing Run’ for each individual burner run. All elbows and intersections that fall within the condensing section of run must also utilize condensing pipe. If there are no runs long enough to utilize condensing pipe, then the system is considered a non-condensing system.

IN-LINE SYSTEMS : If the system requires the simulation of in-line burners, all tie-in burners

(Figure 2.1) must be located no less than the ‘Minimum Distance from Burner to First Elbow or

Intersection’; also reference ‘Maximum Actual Distance Between Tie-Ins for Simulated In-Line

Systems’ to ensure the tie-in distance is not exceeded . Reference Chart 2.2 to determine the

‘Starting Point for Condensing for Simulated In-Line Systems.’ If using an in-line approach, skip to step 5 .

Slope condensing pipe 1/4 in. per every 10 ft. as it approaches the vacuum pump.

2 It is critical that tube mounting begins with the run having the greatest amount of condensing pipe. If installing a non-condensing system, begin with the longest run.

NOTE : Baffle installation must be as close to the vacuum pump as possible and in the section of tubing that allows insertion of the entire length of baffle (refer to page 27 for baffle assembly and placement instructions).

3 Only one hanger is required for each radiant tube spaced approximately 9’-8” apart. For the combustion tube (connects to 16” tube on burner box) space two wire hangers approximately 8 ft. to 9 ft. apart to mount the tube section. Place tubes in hangers with welded seam facing downward and the swaged end of the tube towards the vacuum pump (Figure 3.6).

IMPORTANT!

150,000 to 200,000 BTU/h models must be installed with a stainless steel tube clamp (P/N: TP-220) located at the seam between the primary combustion chamber and the second tube section downstream of the burner control box.

1

Place tube clamps directly over tube seams (Figure 3.8).

2

Slip-fit the radiant tube sections together until tightly connected (install the swaged end of each tube towards vacuum pump). NOTE: If it is difficult to mate the tubes, they may be misaligned.

3

Center tube clamps over the seam where two radiant tube sections connect. If necessary, rotate tube clamps so they will not interfere with the reflector end caps during expansion and contraction of the heater.

4

Tighten tube clamp bolts to secure. When proper compression of 40-60 ft.-lbs. torque is obtained, the tube seam will create a visible mark on the tube clamp. NOTE: Excessive torque may damage the tube clamp.

Figure 3.8 • Tube Connections

Tubes fit snugly together and the tube clamp is centered over the seam.

The tube clamp is tight when proper torque is achieved (normally when seam becomes visible).

Tubes are not fit snugly together and the tube clamp is not centered over the seam.

Installation • Reflector Assembly HLV Series

Reflector Assembly

Reflectors and reflector accessories direct infrared energy to the floor level. The reflector assembly depends on the heater configuration, proximity to combustibles, and space surrounding the heater.

Before you begin assembly, determine if the use of reflector accessories are necessary (see Figure

3.16).

To install the reflectors :

1

Attach the reflector center supports onto radiant tubes at the halfway point between hangers.

2

Slide each reflector section through the hangers and adjust the reflector tension spring into the

V-groove on the top of the reflector. The reflectors should overlap approximately 4 inches for support.

3

To prevent the reflectors from shifting during heater operation, secure reflector sections together using sheet metal screws (field supplied). Allow for unsecured expansion joints between every second and third reflector section following the burners.

4

Install reflector elbows, crosses, tees, etc. atop the applicable fittings if the system uses them.

5

Attach reflector end caps, polished finish inward, to each end of the reflector run and to any exposed elbows, crosses, tees, etc. Secure with reflector end clips provided or field supplied sheet metal screws.

Installation • Combustion Air Requirements

Combustion Air Requirements

This heater has a factory preset air orifice to provide adequate combustion air intake to the unit.

Non-contaminated outside air for combustion must be ducted to the heater if any of the following apply:

• Chemicals such as chlorinated or fluorinated hydrocarbons are present in the space where the heater is installed (typical sources are refrigerants, solvents, adhesives, degreasers, paints, paint removers, lubricants, pesticides, etc.).

• Negative building pressure.

Indoor air supply : If using combustion air intake from indoors, the required volume of the space must be a minimum of 50 ft 3 per 1000 BTU/h (4.8 m 3 /kW) unless the building is of unusually tight construction. If the building is of unusually tight construction with air infiltration rates of less than 0.40 air changes per hour, outside combustion air is typically needed unless the sheer size of the building allows otherwise. Contact the factory for further determination of air infiltration rates.

Outside air supply : Outside combustion air may be supplied via an accessory air duct attached directly over the air orifice. A wall inlet cap (P/N: WIV) must be used with horizontal air intake ducts. It is recommended that the air intake pipe is connected to the heater with a 4 in. diameter flexible air inlet boot (P/N: AIRH) to allow flexibility for expansion (Figure 3.21). Sidewall (horizontal) air intake is preferred.

Refer to Chart 3.3 for limitations on the length and size of air intake ducts.

• A maximum of two 90° elbows is allowed in the ducts.

• Keep air intake opening a minimum of 4 ft. from any exhaust vent openings. Always place vent stacks higher than air intake openings.

• An air intake cap (P/N: WIV) must be installed to prevent blockages. Locate intake cap in an area where dirt, steam, snow, etc. will not contaminate or clog the intake screen.

• Insulated duct or PVC pipe should be used in humid applications to prevent condensation on the outer surface of the intake pipe.

Installation • Gas Supply HLV Series

!

WARNING

An approved connector, suitable for the environment of equipment usage, is required. Visible or excessive swaying, flexing, and vibration of the gas connections must be avoided to prevent failure. In no case shall the gas or electrical supply support the weight of the heater.

IMPORTANT!

The heating system will expand and contract during operation. Allowances for expansion must be made between the connection to the heater and the gas supply.

Excessive bending, kinks, twists, or vibration must be avoided. A flexible gas connection of approved type is required. Flexible stainless steel gas connectors installed in one plane, and without sharp bends, kinks, or twists is recommended.

The gas pipe and connection must be supported independently. Do not install gas supply line in a manner that bears the weight of the heater. Connect the main gas supply line with an approved flexible connector (Figures 3.27-3.28) or, if national or local codes require rigid piping, a swing joint. Heater shall not be connected to the building piping system with rigid pipe or semi-rigid metallic tubing, including copper. When using such material, an intermediate connection device that allows for heater expansion must be used.

The gas outlet must be in the same room as the appliance and accessible. It may not be concealed within or run through any wall, floor, or partition. When installing the heater in a corrosive environment

(or near corrosive substances), use a gas connector suitable for the environment. Do not use the gas piping system to electrically ground the heater.

1

Install a sediment trap / drip leg if condensation may occur at any point of the gas supply line or as required. This decreases the possibility of loose scale or dirt in the supply line entering the heater’s control system and causing a malfunction. NOTE: High pressure gas above 14 Inches W.C. requires a high pressure regulator and ball valve.

2

Form the stainless steel flexible connector into a smooth C-shape allowing 12 in. between the flexible connector’s end nuts (Figures 3.27-3.28).

3

Attach the ball valve to the gas supply pipe. Apply pipe compound to NPT adapter threads to seal the joint. Use only a pipe compound resistant to natural gas and propane.

NOTE: Provide a 1/8 in. NPT plugged tapping accessible for test gauge connection immediately upstream of gas connection to the heater (provided on ball valve).

4

Attach the flexible connector to the adapter and burner control box inlet. Seal the joints.

NOTE: Excessive torque on the manifold may misalign the orifice. Always use two wrenches to tighten mating pipe connections.

5

Final assembly must be tested for gas leaks according to NFPA 54 and all local codes and/or

Standards.

!

WARNING

Testing for gas leaks with an open flame or other sources of ignition may lead to a fire or explosion and cause serious injury or death. Test in accordance with relevant codes of practice.

Operation

!

WARNING

This heater must be installed and serviced by trained gas installation and service personnel only.

Do not bypass any safety features or the heater’s built in safety mechanisms will be compromised.

Burner Lighting Instructions

1 Purge main gas supply line.

2 Rotate heater’s manual ball valve to the “ON” position.

3 Close electrical circuit (turn on thermostat).

4 If the burner fails to light, turn “OFF” gas and wait five minutes before repeating the above procedure.

Burner Shutdown Instructions

1 Open electrical circuit (turn off thermostat).

2 Rotate heater’s manual ball valve to the “OFF” position.

Sequence of Operation

Starting Circuit: Upon a call for heat, power is supplied to the relays at the burner box(es) and vacuum pump. The vacuum pump is energized creating negative air pressure. This allows the differential pressure switch in the burner box(es) to close which completes a low voltage circuit from the secondary side of the transformer to the ignition module. After the ignitor has been powered for seven (7) seconds, the gas valve opens initiating the ignition trial. If flame is not sensed after fifteen (15) seconds, the heater will attempt to re-ignite for a total of three trials for ignition before entering lockout mode.

Single Stage Running Circuit: After ignition, the flame rod monitors burner flame. If sense of flame is lost, the control closes the gas valve within one second and a new trial sequence (identical to the starting sequence) is initiated.

The control can be reset by briefly interrupting the power source.

Two Stage Running Circuit (when applicable ): The second stage on the gas valve is powered directly from the second stage of the thermostat. In order for two stage to flow to a higher output, single stage must be energized as well. The thermostat determines which stage to maintain for the desired temperature.

HLV Series 4.0

Operation • Thermostat • Diagnostics

Thermostat

NOTE: Different thermostats operate according to their particular features. Refer to thermostat specifications for details.

HLV Series heaters require a 24 V, two stage thermostat to operate. The burner control box is equipped with a round terminal strip that accepts three (3) 1/4 in. insulated female spade terminals. Do not supply 120 V to the 24 V connection.

Theoretical Example: The thermostat is set to 65°F. The thermostat’s preset differential for high fire mode is 3°F.

When the temperature drops below the set point of the thermostat (65°F), low fire will activate.

If the temperature continues to drop below the set point by another 3°F (62°F), high fire will activate bringing the temperature back up to the thermostat’s set point.

Diagnostics

The controls will automatically lockout the heater system when an external or system fault occurs.

Lockout: If proof of flame is not established, a component failure occurs or blockages are evident, the heater will enter hard lockout. If lockout occurs, the control can be reset by briefly interrupting the power source. Refer to Chart 4.1 below for a description of the control module diagnostic indicator flash codes.
