MAINTENANCE
1. This construction heater should be inspected before each use. All burner ports should remain clear and the
valve should be inspected for any possible damage. The heater should be test fired before each use. High
pressure air may be used to blow out the inside of the burner.
2. The heater should be inspected annually by a qualified service person.
3. The heater must be kept clear and free from combustible materials, gasoline and other flammable vapors
and liquids.
4. The hose assembly shall be visually inspected prior to each use of the heater. If it is evident there is

INSTALLATION
All natural gas heaters must be installed by a qualified gas fitter and must conform to local installation codes or, in
the absence of local codes, with the National Fuel Gas Code ANSI Z223.1/NFPA 54 and the Natural Gas and
Propane Installation Code, CSA B149.1. The natural gas heater is provided with a ½" male quick disconnect fitting.
The hose assembly used to install this heater must be a Type 1 CGA/AGA approved hose assembly equipped with a
½" female quick disconnect socket to mate with the inlet fitting. Before lighting the heater, all connections must be
leak checked using a soap and water solution. The heater must be installed on a level surface.
FOR A HEATER CONNECTION TO AN LP-GAS SUPPLY CYLINDER
1. The installation must conform with local codes or, in the absence of local codes, to the Standard for the
Storage and Handling of Liquefied Petroleum Gases, ANSI/NFPA 58 and the Natural Gas and Propane
Installation Code, CSA B149.1.
2. The hose assembly used to install this heater must be a Type 1 CGA/AGA approved hose assembly. The
heater must be located at least 20-ft (6.10m) from any LP-gas cylinder.
3. The heater should be installed using a LP-gas cylinder with a minimum capacity of 30-lbs up to a
maximum capacity of 100-lbs.
4. The cylinders used to supply this heater must provide for vapor withdrawal only.
5. The heater must be connected with a “low pressure” regulator and POL inlet fitting. The POL fitting is
connected to the LP-gas cylinder by turning the POL nut counter clockwise and tightened using a wrench.
All connections must be checked for leaks using a soap and water solution or approved leak detector
solution. Use a wrench and turn the POL nut clockwise to disconnect the heater from the cylinder.
6. The cylinder must be disconnected from the heater when not in use.
7. The heater is to be stored indoors, the connection between the LP-gas supply cylinder(s) and the heater
must be disconnected and the cylinder(s) removed from the heater and stored in accordance with Chapter 5
of the Standard for the Storage and Handling of Liquefied Petroleum Gases, ANSI/NFPA 58 and CSA
B149.1, Natural Gas and Propane Installation Code.

LIGHTING INSTRUCTIONS
1. Ensure the heater is connected to the proper source of gas and proper
inlet pressures are supplied. The heater must be installed by a
qualified installer.
2. Set thermostat knob (green button) to high position. Rotate the control
knob (black) counter clockwise to 'PILOT' position. Depress and hold
control knob.
3. Light the pilot burner using a long reach lighter through lighting hole
provided.
Release the knob after 60 seconds. Pilot will remain lit. Main burner
will remain off.
4. Turn control knob counterclockwise to 'ON' position. Main burner
will light.
5. If the main burner fails to light, turn the control knob clockwise to the
'OFF' position, wait 5 minutes and repeat step 3.
6. The green knob controls the thermostat option. This will light and
extinguish the main burner as the temperature fluctuates.
SHUT OFF INSTRUCTIONS
1. Turn the control knob clockwise to the 'OFF' position. Both main
burner and pilot burners will extinguish.
2. Turn off source of fuel.

IMPORTANT NOTES FOR SUCCESSFUL LIGHTING AND OPERATIONAL SAFETY
1. For safety purposes, this heater model is equipped with a “tip over switch” which will prevent the heater from
operating or being lit if it is bumped, jarred, knocked over or positioned on an angle. In order to light and
operate properly, this heater MUST be placed on a flat horizontal surface in an upright position.
CORRECT POSITION
2. The tip over switch is interlocked with the
thermocouple. The connections on the
thermocouple switch must be kept clean and tight at
all times to ensure proper operation of these
components.
Thermocouple block
Tip over switch
3. While the heater unit does not require a filter, the unit must be kept clean and
the burner and pilot assembly must be kept free of dust and dirt to ensure
optimal and safe operation at all times
Store the unit in a clean environment and make sure that the unit is leak
checked and cleaned before every use. Do not clean the unit with volatile
substances. (see maintenance on Page 3)
