•
•
•
•
•
•
•
Vehicle parking areas
Vehicles with lifts or cranes
Storage areas with stacked materials
Lights
Sprinkler heads
Overhead doors and tracks
Dirty or contaminated environments
A critical safety factor to consider before installation is the clearances to combustibles. Clearance to
combustibles is defined as the minimum distance you must have between the tube surface, or reflector,
and the combustible item. Considerations must also be made for moving objects around the tube heater.
The following is a partial list of items from which to maintain clearances:

Trailers
When installing the radiant heating system, the minimum clearances to combustibles for your series tube
heater and system configuration must be maintained. These distances are shown in Chart 2.1 on page 9
and on the burner control box. If you are unsure of the potential hazards, consult your local fire marshall,
fire insurance carrier or other qualified authorities on the installation of gas fired tube heaters for approval
of the proposed installation.
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’s thermostat or in a conspicuous location.
The stated clearance to combustibles represents a surface temperature of 90°F (32°C) above room
temperature. Building materials with a low heat tolerance (such as plastics, vinyl siding, canvas,
tri-ply, etc.) may be subject to degradation at lower temperatures. It is the installer’s responsibility to
assure that adjacent materials are protected from degradation.

3.0 Installation
!
WARNING
Improper installation, adjustment, alteration, service or maintenance can cause property
damage, serious injury or death.
Read and understand, the installation, operating and maintenance instructions
thoroughly before installing or servicing this equipment.
Only trained, qualified gas installation and service personnel may install or service this
equipment.
Design Considerations and Prechecks
Placement of infrared heaters is influenced by many factors. Aside from safety factors, considerations
such as the number of heater or vent elbows that are allowed, maximum vent lengths, ducting of
combustion air and combining exhaust vents are a few examples. All installation manuals, along with
national, state, provincial and local codes, address these issues. It is critical that you read, understand
and follow all guidelines and instructions.
To ensure a properly designed heating system, a layout should be developed for the correct placement of
the heating appliance, vents and combustion air intake ducts. Inspect and evaluate the mounting
conditions, vent locations, gas supply and wiring. Refer Chart 3.1 on page 11 for the recommended
mounting heights and coverages for the model being installed.
NOTE: When heated, materials high in hydrocarbons (solvents, paint thinner, mineral spirits,
formaldehydes, etc.) can evaporate. This may result in odors or fumes being emitted into the
environment. To correct this problem, clean the area and/or introduce additional ventilation. Heaters
installed and serviced in accordance with the installation manual do not emit odors into the environment.
IMPORTANT: Fire sprinkler heads must be located at an appropriate distance from the heater. This
distance may exceed the published clearance to combustibles as posted on the heater. Certain

3.0 Installation • Combustion Air Requirements
AVS Series
Combustion Air Requirements
Combustion air may be supplied to the heater by indoor or outdoor means.
If using combustion air intake from indoors, the required volume of the space must be a minimum of 50 ft3
per 1000 BTU/hr (4.8 m3 /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.
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 (typical sources are refrigerants, solvents,
adhesives, degreasers, paints, paint removers, lubricants, pesticides, etc.).
• High humidity.
• Contaminants such as sawdust, welding smoke, etc.
• Negative building pressure.
• Unusually tight construction where there is an air infiltration rate of less the 0.40 air changes per hour.
Combustion air intake may be located on either the sidewall or roof (see figures 3.15 - 3.18).

!
WARNING
Improperly connected gas lines may result in fire, explosion,
poisonous fumes, toxic gases, asphyxiation or death. Connect
gas lines in accordance to national, state, provincial and local
codes.
IMPORTANT! Before connecting the gas supply to the burner control box:
• Verify that the heater’s gas type (as listed on the rating plate) matches that of your application.
• Check that the gas piping and service has the capacity to handle the total gas consumption of all
heaters being installed, as well as any other gas appliances being connected to the supply line.
• Check that the main gas supply line is of proper diameter to supply the required fuel pressures.
• If utilizing used pipe, verify that its condition is clean and comparable to a new pipe. Test all gas
supply lines in accordance with local codes.
• Test and confirm that inlet pressures are correct. Refer to the heater rating plate for gas type and
the required minimum and maximum pressures (see Chart 3.5). The gas supply pipe must be of
sufficient size to provide the required capacity and inlet pressure to the heater (if necessary,
consult the local gas company). Do not exceed the maximum allowed pressures for the heater,
the space or the gas piping system.

To connect the gas:
WARNING
!
Failure to install, operate or service this appliance in the approved manner may result in
property damage, injury or death. Only trained, qualified gas installation and service
personnel may install or service this equipment.
The installation must conform with local building codes or, in the absence of such codes, the National Fuel
Code (NFPA 54) and in conjunction with ANSI Z21.24/CSA 6.10 “Connectors for Gas Appliances”.
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 Type 1
rubber gas connectors, or other approved connection device, 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 (Figure 3.19) 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. This
will decrease 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. (water column
pressure) requires a high pressure regulator and ball valve.
2
Form the approved flexible connector (field supplied) into a U-shape allowing a maximum of 14 in.
between the flexible connector’s end nuts (see Figures 3.19-3.20).
3 Attach the ball valve (optinal) to the gas supply pipe. Apply pipe compound to NPT adapter
threads to seal the joint. Use only a pipe compound resistant to LP.
NOTE: Provide a 1/8 in. NPT plugged tapping accessible for test gauge connection immediately
upstream of gas connection to the heater.
!
CAUTION
When using a Type 1 rubber flexible gas connector, do not attach the connector nuts directly to the gas
pipe supply. Connector nuts must be installed to an approved adapter.

4.0 Operation • Sequence of Operation
AVS Series
!
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.
Sequence of Operation
Starting Circuit: Upon a call for heat, the fan and transformer is energized by 120VAC from the
thermostat/controller. Once operational static pressure is achieved, the differential pressure switch
closes, sending power to the ignition module. After a seven-second pre-purge, the spark igniters
and the solenoid of the gas valve are simultaneously energized. The trial for ignition is 15 seconds.
Running Circuit: After ignition, the control monitors burner flame through the flame sensors. If sense of
flame is lost, the control immediately sparks (identical to the starting sequence). If flame sense is not
established within 15 seconds, the heater will attempt two (2) additional ignition sequences before
proceeding to lockout mode. The control can be reset by briefly interrupting the power source.

5.0 Maintenance • Routine Inspection
AVS Series
!
WARNING
Personal injury or death may result if maintenance is not
performed by properly trained gas installer or service
personnel. Contact the installing distributor or place of
purchase for service. Do not operate heating system if
repairs are necessary.
Allow heater to cool prior to servicing.
Disconnect power to heater before servicing.
Use protective glasses when maintaining the heater.
Routine Inspection
At least once per year, the heating system should be inspected and serviced by trained gas installation
and service personnel only. This inspection should be performed at the beginning of the heating
season to insure that all heater components are in proper working order and that the heating system
operates at peak performance. Particular attention should be paid to the following items.
•
Blower Motor: Ensure that the squirrel cage in the blower is kept clean. If dirt becomes a problem,
installation of outside air intake ducts for combustion is recommended.
•
Vent pipe system: Check the outside termination and the connections at the heater. Inspect the vent
exhausts for leakage, damage, fatigue, corrosion and obstructions. If dirt becomes a problem,
installation of outside air intake ducts for combustion is recommended.
•
Combustion air intake system (when applicable): Check for blockage and/or leakage. Check the
outside termination and the connection at the heater.
•
Heat exchangers: Check the integrity of the heat exchangers. Replace if there are signs of structural
failure. Check for corrosion and/or buildup within the tube exchanger passageways. Check level both
ways (side to side; front to back).
•
Burner: Check for proper ignition, burner flame and flame sense. Flame should extend directly
outward from burner without floating or lifting.
•
Wiring: Check electrical connections for tightness and/or corrosion. Check wires for damage.
•
Gas Connection: Inspect the integrity of the gas connection to the heater. Check for leaks, damage,
fatigue or corrosion. Do not operate if repairs are necessary and turn off gas supply to the heater.
Contact service personnel.
•
Reflectors: Inspect the integrity of the reflectors for damage, separation, missing or misaligned
sections and that reflector rotation does not exceed 45° from horizontal. Do not operate if repairs are
necessary. Repair or replace as required per the general installation manual.
To maintain effective infrared heating, always keep both sides of the reflector clean. Dirt and dust can
be vacuumed or wiped clean with a soap and water solution. Use metal polish if the reflectors are
severely dirty.
