Preface
GoGaS high intensity heaters represent an efficient and comfortable alternative to conventional
heating systems. The infrared gas fired heater is an atmospherically operated infrared heater
which converts most of the energy applied (natural gas or LPG) into thermal radiation. The
sensible radiation component within the vicinity of persons allows a reduction in the air
temperature, thus leading to energy savings.
The Technology
The GoGaS KMI Novus high intensity heater from the KMI series is a high-quality product with
ratings from 6 kW (21,000 BTU/h) to 36 kW (125,000 BTU/h). The modern injector burner allows
almost pollution-free operation, from the smallest to the largest heater unit, with only one
combustion chamber. The stainless steel combustion chamber is integrated in an insulated
hood. The hot waste gases collect under the hood and pre-heat the gas-air mixture in the
combustion chamber, leading to a maximum degree of radiation. The reflector is made of highly
reflecting material and directs the captured radiation towards the vicinity of persons.

Important
This appliance must be installed in accordance with current connection and installation
regulations and may only be used in adequately ventilated rooms. The installation and operating
instructions must be inspected and understood before installation and before start-up.
Before installation it must be checked whether local gas distributions, gas types and gas
pressures as well as the settings of the appliance are compatible.
General information
GoGaS infrared heaters are manufactured in accordance with ANSI Z83.19-2009/CSA 2.35-
2009. Each appliance is subjected to a function test before it leaves the factory and is preset to
the relevant gas type. For setting up and operating radiation equipment, the following
regulations and guidelines must be complied with.
This heater maybe approved for either indoor or outdoor installation. Not for use in
residential dwellings, refer to Rating plate.
Installation Codes
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.
General Installation and Gas Codes/Electrical Codes
If an external electrical source is utilized, the heater, when installed, must be electrically
grounded in accordance with the National Electrical Code, ANSI/NFPA 70, or current Canadian
Electrical Code, CSA C22.1.
Aircraft Hangar Installation
Installation in aircraft hangars must conform to the Standard for Aircraft Hangars, NSI/NFPA 409
in the US and CAN/CGA B149.1 and B149.2 Installation Codes in Canada
Public Garages
Installation in public garages must conform to the Standard for Parking Structures, NFPA 88A or
the Standard for Repair Garages, NFPA 88B, in the US and CAN/CGA B149.1 and B149.2
Installation Codes in Canada.
Parking Structures
Technical requirements are outlined in ANSI/NFPA 88A (USA)
Warning: Heaters should be installed so that the minimum clearances marked on the heater will
be maintained from vehicles parked below the heater.
Important
These instructions, the layout drawing, local codes and ordinances, and applicable
standards such as apply to gas piping and electrical wiring comprise the basic information
needed to complete the installation, and must be thoroughly understood along with general
building codes before proceeding.
Only personnel who have been trained and understand all applicable codes should
undertake the installation. SRP Representatives are Factory Certified in the service and
application of this equipment and can be called on for helpful suggestions about installation.

Serires KMI - 6 - November 4, 2013
Layout Considerations
1. Because high intensity heaters are un-vented, ensure that adequate ventilation will be
available; most codes require a minimum of 4 cfm per 1000 BTUH of installed heat
capacity in natural gas, 4.5 cfm per 1000 BTUH for propane. 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.

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.
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.

Serires KMI - 18 - November 4, 2013
Operation
Single-Stage High Intensity Heater
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.
Do NOT operate the Infrared Heater if the gas pressure below 6.5” W.C. for natural
gas and 12" W.C. for propane.
Control Operating Sequence
Energise the system by 1). Connecting electricity to unit, 2) Set thermostat to call for
heat. Ignitor will spark after 30 seconds once the system energises, and the solenoid
valve will open permitting gas to flow. The flame sensor will try to sense flame by sending
current of 0.8A or greater to the flame sensor to confirm flame; if the flame sensor does
not sense flame in 15 seconds the solenoid valve de-energises and it will try to light two
more times, if it again fails to sense current it will go in lock out mode (fault mode 1 hour
automatic reset).
Reconnection after shut-down on fault
The device must be disconnected from the electrical supply for a period of at least 5 sec.
Then it must be connected or plugged in again as described above.
Re-ignition
If a malfunction occurs during operation, the ignitor will spark trying to ignite the gas for
the maximum duration of 15 sec. If no current is created within this period, the device
shuts down on fault.
Controlling / Checking Manifold Pressure
Connect the pressure gauge to the manifold pressure test nipple
Switch on the high intensity heater.
Compare the manifold pressure with the specifications on the rating plate and if
necessary correct manifold pressure.

Serires KMI - 19 - November 4, 2013

Annual Maintenance
Close the fuel gas valve and de-energize electrical power to the heater.
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 venturi for about one
minute.
Verify that there are no cracked tiles.
Review the wiring for any loose connections.
