Series S Page - 6 - March 4, 2014
LAYOUT RECOMMENDATIONS
Layout Considerations
1. Because high intensity heaters are un-vented, verify local codes for guidance on air supply and
dilution air. Also see section on Ventilation.
2. Check local codes for mounting requirements and the requirement for flexible gas connectors or rigid
mounting.
3. Do not locate heaters near windy locations such as door openings.
4. Do not locate heaters in very dusty environments
5. Avoid placing heaters below sprinkler heads or provide more than adequate clearance.
Spot Heating
High intensity heaters are ideal for spot heating applications. The following are key considerations to
the success of the application:
1. Minimize any wind in order to maximize the effect of the radiant heat.
2. Placing two smaller heaters opposing each other will be more comfortable than placing one
large heater.
3. Hang the heaters back and at an oblique angle (rather than directly overhead) in order to
maximize the exposure of the peoples’ bodies to radiant heat.
The following charts are intended for guidance only. Specific applications may require other parameters.

CLEARANCE TO COMBUSTIBLES
The stated clearance to combustibles represents a surface temperature of 90°F (50°C) above room
temperature. Building materials with low heat tolerance (such as plastics, vinyl siding, canvas, tri-ply,
etc…) maybe subject to degradation at lower temperatures. It is the installer’s responsibility to assure that
adjacent materials are protected from degradation.
WARNING
Clearances as marked on the heater body must be maintained from vehicles parked beneath. Signs should
be posted identifying any possible violation of the clearance distances from the heater in all vehicle areas.
Clearance to combustibles must be maintained according to the following chart. In storages areas, signs must
be posted to specify the maximum permissible stacking height.
Adequate clearance to sprinkler heads must be maintained.

Figure 3 illustrate typical rigid and chain mounting configurations for the Series S heaters; verify which
is permissible by local codes.
Heaters must be hung at an angle between 10° and 35°. Typically, at the walls they are at 35° facing
into the building. The gas manifold must always be at the lower side of the heater.
Minimum 3/16diameter S hooks and No. 1/0 chain (200 lb./ 91 kg working load) is recommended.
Close S hooks after installation.
Never use a gas line as a hanging support and never locate gas or electric lines over the heaters.
Maintain clearance to combustibles.
Ensure that there is a plugged tap upstream of the heater or a fitting on the valve itself to verify
incoming pipeline pressure.
Do not leave the heater connected when pressure testing the pipeline. The high pressure will damage
the equipment.

Typical Wiring Layouts
* In some cases the 120/24 volt transformer can be positioned
prior to the thermostat. In this case, evaluate the contact
load across the thermostat contacts, as the load created by
the operating heaters may be too great. In that case a relay
should be used.
* When using a 24 volt system, be sure that the control
transformer being used has enough VA (volt amp) rating
for the heater control system being used. Example:
Operating five 24V model "S" heaters using one transformer,
each control or heater requires 20 VA. 5 units x 20VA = 100VA
transformer capacity minimum.
INSTALLATION
Electric
Figure 4 illustrates typical wiring arrangements for the Series S heater. Two options are available; 230V and 24V
supply. Up to six heaters may be operated from one thermostat. (Verify thermostat electrical capacity if non SRP
product is used.)
Ensure the heaters are properly grounded.
If mechanical exhaust is used in the building, it is typical to interconnect these in the heater circuit as
shown in Figure 4.
Perform all work in accordance with local codes or the National Electric Code ANSI/NFPA 70 or
Canadian Electrical Code CSA C22.1.

VENTILATION / CONDENSATION
Ventilation
Buildings using high intensity radiant heaters require ventilation. High Intensity type heaters are considered
un-vented gas fired appliances, requiring ventilation to supply combustion air and dilute/remove the products
of combustion.
Requirements for combustion air supply and dilution air vary by jurisdiction, building type and specific
installation details. See local codes for guidance. In general, where heaters are installed without direct
outside combustion air, fresh air ventilation must be provided to building space (3 cfm per 1000 BTU/Hr in
Canada, 4 cfm per 1000 BTU/Hr in the USA), Verify applicable local codes in the USA as requirements
change by jurisdiction.
Mechanical exhaust should be electrically interconnected with the heaters and should always be
installed in conjunction with inlet air openings. See “Block Diagram for Interconnecting
Fan/Humidistat” above for details.
Inlet air opening should be relatively small and distributed over the operating area of the heaters.
They must always be located below the level of the heaters. One square inch of net free inlet area per
1000 BTUH is recommended.
Figure 5: Block Diagram
Condensation
The products of combustion for natural gas contain up to 1 liter of water per 100,000 BTU consumed. This
may add substantial amounts of moisture to the building air environment and may become a problem of
condensation on cold surfaces within the building. This is particularly true for poorly insulated metal roof
decks or structural steel framing.
To decrease condensation, increase mechanical ventilation.
Ensure that continuous waterproof barriers are used on the inside of all insulated surfaces.
Ensure that exhausters pull air from the entire space and across the condensing surface.
Humidistat controls may be integrated into the electrical control circuit of the heaters.

When using a humidistat to control exhaust

Depending on fan horsepower, a relay may or

Series S Page - 15 - March 4, 2014
OPERATION / MAINTENENCE
Operation
Ensure the gas supply line has been purged.
Open all gas cocks to the heaters and electrically energize the system.
Follow the instructions on the heaters Lighting Instructions Label. Check to ensure that the thermostat starts
and shuts down the system.
Control Operating Sequence—Direct Spark Ignition
1. The thermostat calls for heat.
2. The combination gas valve opens and the spark igniter sparks in an attempt to light the fuel at the
face of the ceramic. The spark will continue for 15 seconds
3. Once flame is established (prior to complete steady-state conditions) the flame sensor signals the
module and sparking stops. If the burner does not light in 15 seconds, the system will lockout, i.e.
electric energy to the gas valve and electronic module is cut. The lighting sequence may be reset
by an interruption of the electric power supply.
4. Once operating, the heater will continue to do so until the thermostat is satisfied; shutting the gas
valve.
Annual Maintenance
1. Close the fuel gas valve and de-energize electrical power to the heater.
2. With an air hose regulated to no more than 15 psig blow away accumulated dust. Blow across the
face of the ceramic tiles, not directly at them. Blow into each venturi for about one minute.
3. Verify that there are no cracked tiles.
4. Review the wiring for any loose connections.
