1.Installation Requirements.
1.1Health and Safety
A.Heater is intended for heating non-residential indoor spaces and should only be installed where flammable gases or vapors are not present.
B.Heaters can be suspended horizontally or at any angle along the axis of the tubes but can only be rotated about the burner head 0 to 55°. See section 1.3 for clearance dimensions.
Doc No 700106 (06-15), Page 2
C.The installation must conform with local building codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas and Propane Installation Code, CSA B149.1.
D.The unit shall be electrically grounded in accordance with National Electric Code ANSI/NFPA 70 and Canadian Electrical Code CSA C22.1.
E.The heater may be installed in aircraft hangars in accordance with the Standard for
Aircraft Hangars, ANSI/NFPA 409 and in
automotive garages when installed in accordance with the Standard for Parking Structures, ANSI/NFPA 88A, or the Standard for Repair Garages, ANSI/NFPA 88B, or the Canadian Natural Gas and Propane Installation Code, CSA B149.1, and are so marked.
Ensure that minimum clearances will be maintained to vehicles parked below the heater.
F.The standard heaters are approved for installations between 0 - 2000ft (0 - 610m) above sea level for the US and 0 - 4500 ft (1370m) above sea level for Canada. Conversion kits are available for installations above these heights in the USA.
G.Massachusetts Requirement: If the heater is being installed in the Commonwealth of Massachusetts, this unit must be installed by a licensed plumber or licenced gas fitter.
1.2Heater Suspension
Attachment to the heater support lugs should be made by D shackle. The hanging attachments to overhead steelwork etc. have
to be designed and produced in accordance with sound engineering practices. They must be adequately fixed and designed to carry the whole weight of the heater. In the event of suitable roof steelwork being unavailable, additional steelwork should be fitted to enable vertical hangers to be used for suspending the heaters.
These methods are illustrated in Figure 1. If there are any doubts as to the strength or suitability of roof steelwork to which heaters are to be suspended, please refer to a Consultant, Architect or owner of the building.
It is recommended that the heater is raised to its final position once the assembly of the emitter tube/bracket/reflector has been completed. Longer tube assemblies may be raised in more than one sub-assembly with final emitter tube connection made in the air.
Ensure that the installer uses the burner roof support mounting bracket when suspending the heater. This is situated on the front of the burner. When packed the bracket is reversed and must be turned to its correct state for mounting. (ref page 15)
WARNING:
If not installed, operated and maintained in accordance with the manufacturer’s instructions, this product could expose you to substances in fuel or from fuel combustion which are known to the state of California to cause cancer, birth defects or other reproductive harm.

1.3Clearance to Combustibles.
Minimum clearance to combustibles are shown in Table 1 below.
IMPORTANT:
The stated clearance to combustibles represents a surface temperature of 90°F (50°C) above room temperature. Building material 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.

1.4Gas Connection and Supply
WARNING: Before installation, check that the local distribution conditions, nature of gas and pressure, and adjustment
of the appliance are compatible.
The gas connection on the heater is ½” N.P.T internal thread.
Injector sizes and manifold pressure for the burners are shown in the table 3. The gas supply piping and connections must be installed so that the minimum pressure stated is achieved.
A gas shut off valve and union should be fitted in the gas supply line close to the heater and a ⅛” N.P.T plugged tapping, accessible for test gauge connection, provided immediately upstream of the appliance gas inlet.
It is essential to provide some flexibility in the final gas connection by use of an approved flexible gas connector. (See Fig 4.)
Take care when making a gas connection 
to the heater not to apply excessive turning
force to the internal controls.
Care must be taken to observe the pipe bend diameter of 12” (30cm) and pipe displacement distance of 3” (7.62cm).
The correct installation as shown will allow 
for approx 4” of movement due to
expansion.
* Connector must be certified for use on a radiant tube type infrared heater and must comply with Standard for Connectors for Gas Appliances, ANSI Z21.24/CSA 6.10 or with the Standard for Elastomeric Composite Hose and Hose Couplings for Conducting Propane and Natural Gas, CAN/CGA 8.1.
For heaters up to 150,000Btu/h, ½” ID x 24” long
For heaters 150,000Btu/h and above, ¾” ID x 36” long NOTE: For Canada all heaters MUST use a hose 36” long (See Table 3)

WARNING: FIRE OR EXPLOSION HAZARD - It is essential to provide some flexibility in the final gas line connection by use of an approved flexible connector as shown in the drawings. Expansion of the radiant pipe occurs with each firing cycle causing the burner to move with respect to the gas line. This can result in a gas leak producing an unsafe
condition.
Doc No 700106 (06-15), Page 6
CONNECTOR MUST BE INSTALLED IN A “U” CONFIGURATION. FOR HEATERS UP TO 150,000 BTU/H, A 24” LONG CONNECTOR OF AT LEAST ½” ID MUST BE USED. FOR HEATERS ABOVE 150,000 BTU/H, A 36” LONG CONNECTOR OF AT LEAST ¾” NOMINAL ID MUST BE USED.

1.5.2 Multiple burner configuration via independently powered two stage thermostats. Refer to figures 6c and 6d.
Note: If the thermostat has an independent power supply, all burners in the zone to be controlled MUST be Slave burners.
The maximum number of Slave burners per thermostat is dependent on the maximum power output of the thermostat selected.
Each ‘Slave’ burner is rated at 1.6VA 24VAC 60Hz.
The external two stage thermostat is powered via its own power supply and must output to each Slave burner - 24VAC for low fire to terminal W1 and 24VAC for hi fire to both terminals W1 and W2
Refer to thermostat manufactures literature for details.

NOTES:-
Power On light is permanently illuminated when 120V / 60 Hz AC external supply is connected to burner. Additional wiring is required to install an optional extra thermostat and / or time clock.
Wire specification:- 18 AWG (1.0mm²), Tri-rated, 105°C
If any of the original wire as supplied with the appliance must be replaced, it must be replaced with wiring material having a temperature rating of at least 220°F/105°C
Doc No 700106 (06-15), Page 10
1.6 Vent Requirements and Details
1.6.1 Unvented units
Heaters may be installed unvented providing the governing building codes are met and consideration is properly given to possibilities of condensation on cold surfaces.
Installation shall meet the following requirements when unvented:
•Natural or mechanical means shall be provided to supply and exhaust at least 4 CFM per 1000 BTU per hour input of installed heaters.
•Combustion gases shall not impinge on combustible materials.
1.6.2 Vertical venting
The heater can be installed with a vertical vent.
All vent piping should be adequately supported from the building structure and terminated with an approved terminal. The maximum recommended vent length is 25ft (7.6m) with a maximum of two elbows. All connections should be properly sealed. refer fig 7a
1.6.3 Horizontal venting
Individual units can be vented horizontally through side walls. Recommended terminals are Part Numbers 111848 for 4” and 111850 for 6”.
Distances from adjacent public walkways, adjacent buildings, openable windows and building openings, consistent with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas and Propane Installation Code, CSA B149.1.
The maximum recommended vent length is 25ft (7.6m) with a maximum of two 90° elbows. However runs up to 12ft (3.6m) can use 4” (101mm) vent pipe. Runs over 12ft (3.6m) should always use 6” (152mm) vent pipe.
An approved clearance thimble is required when the flue pipe passes through combustible materials. Follow the requirements of the thimble manufacturer.
Standard vent terminals must extend at least 6” (152mm) from the wall and at least
Doc No 700106 (06-15), Page 11
24” (609mm) from any combustible overhang. This protects the building material from degradation by the vent gases.
Vent joints should be sealed and secured according to the vent manufacturers instructions. Should condensation occur the vent should be shortened or insulated.
The terminal should be at least 3ft (0.91m) from any air intake to the building.
The vent terminal must be installed at a suitable height above the ground to prevent blockage by snow.
1.7Fresh Air Intake
Whenever the heater is installed in locations where airborne dust or other pollutants are present, a fresh air supply should be ducted to the burner.
If the heater is equipped with ducted combustion air, the vent terminal must be at least 3ft (0.91m) away from the air inlet and located higher than the inlet.
A fresh air duct of 4” (101mm) diameter should be installed from the fresh air to the air intake connection on the fan housing. A flexible jointing piece should be installed at the fan connection with hose clamps to facilitate expansion and contraction.
The maximum recommended length air duct is 25ft (7.6m) and the maximum number of elbows is two. The minimum length is 18” (456mm).
The location of the fresh air duct inlet must be where it will receive dust free clean air. An inlet cap with bird screen must be fitted at the inlet of the duct. If the duct inlet is located above the roof the underside of the inlet terminal must be at least 2ft (0.61m) above roof level (or above projected snow load) and at least 10” (254mm) above any projection on the roof within 7ft (2.1m) of the inlet. Intake pipe, fittings and sealant are not furnished by the manufacturer. Refer fig 7c & d.
Note the vent terminal must NOT be installed below the fresh air intake, and should have a minimum separation distance of 36” from the air intake.
Note The vent terminal should be installed so as to be in the same atmospheric pressure zone as the combustion air inlet of the appliance.
Figure 7.a Vertical Venting.
Approved clearance thimble is required when the flue pipe extends through combustible materials. Follow the requirements of the thimble and/or Category III vent pipe manufacturer.
Figure 7.b Horizontal Venting (plan view shown).
Approved clearance thimble is required when the flue pipe extends through combustible materials. Follow the requirements of the thimble and/or Category III vent pipe manufacturer.
Note The vent terminal should be installed so as
to be in the same atmospheric pressure zone as the combustion air inlet of the appliance.
Note the vent terminal must NOT be installed below the fresh air intake, and should have a minimum separation distance of 36” from the air intake.
