non-residential indoor spaces and should only be installed where flammable gases or vapors are not generally present.
B. Heaters may be suspended either horizontal
or at any angle. See section 1.3 for clearance dimensions.
Doc No 700101 (06-15), Page 2
C. The installation must conform with local
D. The unit shall be electrically grounded in
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.
accordance with National Electric Code ANSI/NFPA 70 and Canadian Electrical Code CSA C22.1.
Page 3
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) for the US and 0 - 4500 ft (1370m) for Canada. Conversion kits are available on 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.
1.2 Heater Suspension
Attachment to the heater support lugs should be made by D shackle. The hanging attachments to overhead steelwork etc. must be purpose made to sound engineering practice or supplied by others. 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 tube/ bracket/reflector has been completed. Longer tube assemblies may be raised in more than one sub-assembly with final tube connection made in the air.
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.

1.4 Gas 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 4. 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 ” 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 minimum pipe bend diameter (minimum 10” - 250mm, maximum 14” - 350mm) & pipe expansion distance (minimum 1” - 28mm, maximum 3¾”) - 95mm.
The correct installation as shown will allow for approx 4” of movement due to
expansion.

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 gasses 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.
Maximum length of vent is 25ft (7.6m) with two
- 90° elbows.
Runs of 12ft (3.6m) or shorter can use 4” (101mm) dia. vent. Runs over 12ft (3.6m) should 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 and/or vent pipe manufacturer.
Standard vent terminals must extend at least 6” (152mm) from the wall and at least
24” (609mm) from any combustible overhang. This protects the building material from degradation by the vent gasses.
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.
1.7 Fresh 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) dia. 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.

2.2 Assembly Notes.
Please read these assembly notes in
conjunction with the correct assembly drawings (figs 9 to 19).
2.2.1 Tubes
Each heating unit has two types of emitter tube. For details of the tube types and position please refer to the table (page 13 of this instruction manual).
Identify and position tubes on saw horses. For
aesthetics it is advisable to position all tube seams facing down. Position coupling
fastener so that these cannot be seen from beneath the heater.
Mark out the position of the bracket centers from the dimensions shown on the assembly drawings.
2.2.2 Turbulator Strips and Burner Inserts
Ensure that the correct turbulator or burner insert is fitted, as this could void your warranty if they are incorrectly fitted or omitted when necessary.
2.2.2.1 Turbulator Strips
Turbulator strips should be inserted (when required) into the correct tube exactly as indicated in the assembly drawings.
Locate turbulator strip sections. Install the first turbulator strip into the open end of the last tube (only after it has been suspended and connected to the previous tube.)
Interlock the next section of turbulator strip as shown in the diagram below.
Doc No 700101 (06-15), Page 14
Page 15
2.2.2.2
Where a heater configuration requires more than three turbulator strips and has the exhaust heat exchanger tube adjacent to an “L” or “U” heat exchanger tube, refer to the diagram below for positions.
Slide the connected sections into the tube(s). Add further strips to form the correct length required.
For specific configurations see detailed assembly diagrams on pages 20 to 30.
Fit three turbulator strips here

Model 200 S50 fan orifice plate
This model has a different fan orifice plate (Part No.269939) to all other models in the range. It is supplied with every burner as a loose item and should be discarded if not needed. This must be fitted to the 200 S50 model only.
Remove the four fixing screws securing the existing orifice plate, then fit the replacement orifice plate with the correct air inlet hole orientation as shown in the picture opposite.
Note: There should be 22 10mm x 10mm square holes in the replacement plate.
Fit the remaining turbulator strips here

2.2.2.2 Burner Inserts
The burner insert (when required) is inserted into the first heat exchanger tube from where it is joined to the second tube.
2.2.3 Brackets
There can be various styles of brackets supplied with these heaters:
2.2.3.1 Suspension Brackets
2.2.3.1.1 Fixed suspension bracket assembly part #270126 & tube straps part #270572.
ONLY used as the first suspension bracket positioned CLOSEST TO THE BURNER.

Slip the suspension first bracket assembly ­part #270126 onto the first section of tube in the position as indicated on the assembly drawing.
Locate the tube strap assembly part #270572 and loosen the nut and bolt.
Position the strap over the tube and hook the two straps onto the suspension bracket.
Finally tighten the nut and bolt to secure the bracket onto the emitter tube.
2.2.3.1.2 Suspension brackets #270126 with
no tube straps. For ALL other suspension
brackets
Once the emitter tubes have been assembled using the couplers (see section 2.2.4), position all other suspension brackets part #270126 onto the tube(s) in their relevant positions as shown on the assembly drawing.
REFLECTOR BRACKET #270569
Locate a suspension support bracket and remove the bolt fixing the strap to the bracket.
Position the bracket over the emitter tube and loosely replace the bolt.
Roughly position the support brackets in place along the tube assembly as indicated on the assembly drawing. The positioning may need to be adjusted when the reflector is added.
2.2.4 Couplers
The couplers are used for joining radiant tubes and U or L bends.
Slide the coupling onto the end of the existing emitter tube. Slide the end of the next tube into the other side of the coupling.
Doc No 700101 (06-15), Page 16
Page 17
With both tube ends pushed fully into the coupling and the bolts towards the bottom, using a 9/16” wrench, tighten the coupling bolts moving between each bolt in sequence to ensure equal pressure is applied to each bolt.
Complete assembly by drilling and screwing self tapping retention zip screws.
At this point raise the tube assembly into
position and suspend from previously fixed chains (Working Load 100lb). Longer tube assemblies may be raised in more than one sub-assembly with final tube connection made in the air.
2.2.5 Reflectors.
All reflectors must be positioned/ attached to the brackets exactly as detailed in the assembly drawings.
After removing the coloured protective plastic coating (where fitted), slip the reflectors through the suspension brackets until they overlap each other.
The first two reflectors are assembled and overlapped by a pre determined distance, as shown on the assembly drawing, and are fixed onto the emitter tube using the reflector support bracket part #270569.
Each reflector must OVERLAP the
previous one as indicated by their individual assembly sheets.
Reflectors. Note: each reflector must overlap the previous one
Reposition the reflector support bracket if necessary then tighten the clamp bolt.
These two reflectors are fixed in place by tightening the fixing screws/locknuts as below. These are known as ‘non-slip’ overlaps.
TIGHTEN SCREWS TO FIX REFLECTOR
The next reflector is assembled and overlapped by the pre determined distance. The reflector is fitted onto the emitter tube using another reflector support bracket part #270569.
Reposition the reflector support bracket if necessary, then tighten the clamp bolt.
These overlapped reflectors are allowed to ‘float’ within the support bracket by leaving a minimum of 1/8” gap of the fixing screws before tightening the locknuts. These are known as ‘slip’ overlaps.

Further reflectors are assembled and overlapped onto the emitter tube by alternating ‘non-slip’ and ‘slip’ until complete length is covered.
Continue this method to the final reflector/ support bracket.

2.2.7 Bend(s) (where fitted)
The heater can be installed with 1 or 2 90° bends or a 180° U bend.
Slide the bend into the open end of the coupler ensuring that the screw stop has butted up to the tube ends. Refer to 2.2.4 for fastening.

2.2.8 Burner/Fan Assembly.
Slide the burner assembly onto the open tube end, ensuring it is fully engaged. Secure with set screws.
For the purpose of unvented applications, a 4” 90° elbow should be used on the terminating end of the radiant tube sections and completed using a vent cap.
Connect Gas and Electrical supplies as described in sections 1.4 and 1.5.

3. Start Up Instructions.
These appliances should be commissioned by a qualified mechanical contractor.
3.1 Tools Required.
The following tools and equipment are advisable to complete the tasks laid out in this manual.
Leather Faced Gloves
Phillips Screwdriver
Suitable alternative tools may be used.
Small Flat Head Screwdriver
Large Adjustable Wrenches for fitting Of Gas Flex.
½” Wrench
5/32” (4mm) Allen Wrench
3.2 Start Up Procedure
Inspect installation and ensure that it has been carried out in accordance with these instructions. Ensure that electrical and gas supplies are isolated.
The gas supply should be purged and tested for leaks in accordance with local and National Safety codes.
Open shut off gas valve and test gas connections for leaks using soap solution.
Open the control housing door by unscrewing the securing screw. Ensure all internal components are securely fixed and all connections securely made.
Switch on the electrical supply to start the heater and observe the correct start up sequence. Ensure that the setting of any time clock and thermostat are such that the heating system will be required to operate.
The fan will start to run and the ‘power on’ lamp will illuminate. Safe-start checks are carried out automatically.
After the fan has run up to full speed and a satisfactory vent pressure condition has been established, the ignition sequence will commence. The spark ignition will be energized producing a spark at the ignition electrode. The gas solenoid valve will energize at the same time and the ‘burner on’ lamp will illuminate. If the ignition is successful, the flame is detected by the flame sensing probe and the ‘burner on’ lamp will remain on.
If ignition is unsuccessful, after approximately 15 seconds the gas valve will close and the spark ignition will de-energize.
For approximately 30 seconds the fan will purge the system, then re-ignition will be attempted. After 2 further attempts at ignition the control unit will ‘lock-out’, the ‘power on’ lamp will remain illuminated and the fan will run for 120 seconds and then stop.
To reset after ‘lockout’ switch off the power supply to the system and wait 2 minutes. Then turn the power on. If repeated ‘lockout’ occurs, investigate the cause.
Set burner gas pressure as follows: Switch off the power supply to the heating system.
Connect a ‘U’ tube or digital manometer to the pressure test point provided on the combination gas control valve.
Remove the cover from the pressure regulator to reveal the adjusting screw.
Start the heater and using a suitable screwdriver adjust the pressure regulator, turning the screw clockwise to increase the pressure or counter-clockwise to decrease the pressure.
Set the pressure to appropriate inches w.c. from the table of gas pressures and orifice plate dimensions for correct heater description. (See section 1.8 page 12)

Multimeter
Doc No 700101 (06-15), Page 31
Page 32
To enable post purge ensure that the setting of any time switch and thermostat are such that the heating system will be required to turn off.
Switch off the power supply to the heating system. Disconnect manometer, then secure screw in pressure test nipple.
Check the operation of the flame safeguard equipment as follows:
With the heater running normally, switch off the gas supply at the shut off valve. The heater should attempt to relight then ‘lock-out’ should occur. This is indicated by the ‘power on’ lamp being illuminated and fan running, but the ‘burner on’ lamp being off.
Check the operation of the pressure proving switch as follows:
With the heater running normally, pull off the silicone rubber tube connecting the vacuum switch to the combustion chamber. The burner should shut off within 4 seconds .
Replace the tube securely and observe that the heater proceeds to ignite in the normal way.
Close the controls door and secure with the screw.
