Hazards:

For maximum safety the building must be evaluated for hazards before installing the heating system.

Examples include, but are not limited to:

• Gas and electrical lines

• Combustible and explosive materials

• Chemical storage areas

• Areas of high chemical fume concentrations

• Provisions for accessibility to the heater

• Adequate clearances around air openings

• Combustion and ventilating air supply

• Vehicle parking areas

• Vehicles with lifts or cranes

• Storage areas with stacked materials

• Lights

• Sprinkler heads

• Overhead doors and tracks

• Dirty, contaminated environment

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 to maintain clearances from:

Combustible items:

• Wood

• Paper

• Fabric

• Chemicals

• Paint

• Parked vehicles

• Gasoline

• Storage racks

Moving Objects:

• Overhead doors

• Vehicle lifts

• Cranes

• Hoists

When installing the tube heating system, the minimum clearances to combustibles for your Series tube heater and system configuration must be maintained. These distances are shown in Chart 1.1 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 fo 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.

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 infra-red 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 burner control box, tubes, vents and combustion air intake ducts. Inspect and evaluate the mounting conditions, vent locations, gas supply and wiring.

When designing an infra-red radiant heating system, consider the following:

• Has the building’s heat loss been evaluated?

• Does the design meet the needs of the space?

• Have recommended mounting heights been observed?

• Have all clearance to combustible situations been observed?

• Is the supply (burner) end of the heater located where more heat is required?

• Is it best to offset the heaters and/or rotate the reflectors towards the heat zone?

• Are extra guards, side shields, ‘U’ or ‘L’ reflector covers required?

• Does the heater require outside fresh air for combustion?

• Is the environment harsh or contaminated (requiring outside air for combustion)?

• Are chemicals or vapors a concern (requiring outside air for combustion or additional ventilation)?

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

Sprinkler systems containing propylene glycol or other 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.

The effective infra-red surface temperature of a person or object may be diminished with wind above 5 mph. The use of adequate wind barrier(s) may be required.

Factory recommended mounting heights are listed as a guideline. If infra-red heaters are mounted to low or to high, they may result in discomfort or lack of heat. Detroit Radiant Products Company generally recommends observing the recommended mounting heights to optimize comfort conditions. However, certain applications such as spot heating, freeze protection, outdoor patio heating or very high ceilings may result in the heaters being mounted outside of the factory recommended mounting heights.

• Separate air intake duct from vent pipe a minimum of 4 ft. Also, place vent pipe higher than

adjacent air intake duct.

Gas Supply

!

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 and

the installation complies with national and local codes and requirements of the local gas company.

Unless otherwise noted on the rating plate, this infra-red heater is designed and orificed to operate

on standard BTU gas. Contact the factory if utilizing non-standard BTU gas.

HIGH ALTITUDE: Installation of this tube heater is approved, without modifications, for elevations

up to 6,000 feet (1,829 m) MSL (sea level) in the United States. Contact the factory for

installations above these elevations.

• 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.

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 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 (Figure 3.29) 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 in. W.C.P. (water column pressure) requires a high pressure regulator and ball valve.

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 is energized. Once operational static pressure is achieved, the burner pressure switch will close initiating the ignition sequence. After a 5-second delay, the globar is energized for 45 seconds and the control allows the gas valve to open.

The trial for ignition is 8 seconds. If flame sense is not established within 8.5 seconds, the heater will attempt two (2) additional ignition sequences before proceeding to soft lockout. Soft lockout automatically retries after one (1) hour or the control can be reset by briefly interrupting the power source.

Running Circuit: After ignition, the flame rod monitors burner flame. If sense of flame is lost, the control immediately acts to reignite the gas-air mixture (identical to the starting sequence). If flame sense is not established within 8.5 seconds, the heater will attempt two (2) additional ignition sequences before proceeding to soft lockout. The control can be reset by briefly interrupting the power source.

Thermostat

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

Detroit Radiant Products Company has made a diligent effort to provide product information and illustrate the products in this literature accurately; however, such information and illustrations are for the sole purpose of identification, and do not express or imply a warranty that the products are merchantable, or fit for a particular purpose, or that the products will necessarily conform to the illustrations or descriptions. Except as provided below, no warranty or affirmation of fact, expressed or implied, other than as stated in the “LIMITED WARRANTY” above is made or authorized by Detroit Radiant

Products Company.

Product Suitability.

Many jurisdictions have codes and regulations governing sales, construction, installation, and/or use of products for certain purposes, which may vary from those in neighboring areas.

While Detroit Radiant Products Company attempts to assure that its products comply with as many codes, it cannot guarantee compliance, and cannot be responsible for how the product is installed or used. Before purchase and use of a product, review the product applications, and all applicable national and local codes and regulations, and be sure that the product, installation, and use will comply with them. Certain aspects of disclaimers are not applicable to consumer products: e.g., (a) some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you: (b) also, some jurisdictions do not allow a limitation on how long an implied warranty lasts, consequently the above limitation may not apply to you: and (c) by law, during the period of this limited warranty, any implied warranties of implied merchantability or fitness for a particular purpose applicable to consumer products purchased by consumers, may not be excluded or otherwise disclaimed.

Prompt Disposition.

Detroit Radiant Products Company will make a good faith effort for prompt correction or other adjustment with respect to any product which proves to be defective within limited warranty. For any product believed to be defective within limited warranty, first write or call dealer from whom the product was purchased. Dealer will give additional directions. If unable to resolve satisfactorily, write to Detroit

Radiant Products Company at address below, giving dealer’s name, address, date and number of dealer’s invoice, and describe the nature of the defect. Title and risk of loss pass to buyer on delivery to common carrier. If product was damaged in transit to you, file claim with carrier.
