3.0 Installation • Design Considerations and Prechecks

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.

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 infrared 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 combustibles 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 wind barriers required? The effective infrared surface temperature of a person or object may be diminished with wind/drafts above 5 mph.

• 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 to avoid an inadvertent discharge. This distance may exceed the published clearance to combustibles. Certain applications may require the use of high temperature sprinkler heads or the relocation of the heaters.

CAUTION

Fire sprinkler systems containing propylene glycol, antifreeze or other potentially ﬂammable substances shall not to be used in conjunction with this heater without careful consideration for and avoidance of inadvertent discharge hazards. For further information consult NFPA 13. Always observe applicable state and local codes.

3.0 Installation • Design Considerations

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. The heaters themselves, when installed and serviced in accordance with the installation manual, do not emit foul odors into the environment.

Design Scenario:

A tube heater system is being installed in a 90’ (L) x 50’ (W) x 14’ (H) space. Two overhead doors are located at one end and an equipment storage area on one side. The calculated heat load is 400,000 BTU/h.

3.0 Installation • Optional Elbow or U-Bend Accessory Conﬁguration

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

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.

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

tube clamp.

Determine the location of the burner control box and note the placement of the mounting chains.

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.

Page 31

3.0 Installation • Gas Supply

• 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 3.8). 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 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 3.30) or, if national or local codes require rigid piping, a swing joint. See the safety messages at the beginning of this section.

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.

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 (ﬁeld supplied).

Page 32

3.0 Installation • Gas Supply

Form the stainless steel ﬂexible connector (supplied) into a smooth C-shape allowing 12 in. between

the ﬂexible connector’s end nuts (see ﬁgure 3.30).

Attach a ball valve (ﬁeld supplied) 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 (typically provided on ball valve).

CAUTION

When using a stainless steel ﬂexible connector, do not attach the connector nuts directly to the gas pipe supply. Connector nuts must be installed to an approved adapter.

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.

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 NFPA or local codes.

5.0 Maintenance

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: Annual oiling of the blower motor with SAE oil will extend bearing life signiﬁcantly.

Motors with sealed ball bearings (no oil ports) do not require oiling. 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.

Check lubrication instructions on motor. If oiling is required,

add three to four drops of SAE 20 electric motor oil:

• After three years or 25,000 hours of operation (light-duty)

• After two years or 8,000 hours of operation (medium-duty)

• Annually or after 1,500 hours of operation (heavy-duty)

• 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.

• 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.

Never over-oil the motor, or premature failure may occur.

NOTICE

• Reﬂectors: Inspect the integrity of the reﬂectors for damage, separation, missing or misaligned

sections. 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 up or wiped with a soap and water solution. Use metal polish if the reﬂectors are severely dirty.

Contact service personnel if repairs are necessary. Do not operate unit.
