SECTION 4: MINIMUM CLEARANCES TO COMBUSTIBLES
The heater shall be operated only on a NON-COMBUSTIBLE, level floor. Minimum clearances to combustible walls
and ceilings are listed below:

WITHOUT REFLECTOR
SECTION 5: GAS CONNECTIONS AND REGULATION
5.1.
The installation must conform with local codes, or in absence of local codes, with 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.
5.2.
This heater is intended for construction heating and it must never be used for residential/domestic
heating.
5.3.
Connect to the supply tank or manifold in accordance with the latest edition of National Fuel Gas Code
(ANSI Z223.1/ NFPA 54) and local building codes. Authorities having jurisdiction should be consulted
before the installation is made.
5.4.
Pipe joint compounds must be resistant to the action of liquefied petroleum gases.
5.5.
Where local codes do not prohibit, a C.S.A or U.L. approvedflexible connection is recommended between the
rigid piping and the heater. A union and an approved shutoff valve should be installed
before the control valve inlet. The shutoff valve should be installed within 6 feet of the union.
5.6.
This appliance is equipped with a manual gas valve and an appliance regulator. The maximum supply
pressure to the appliance is 14" W.C. or ½ P.S.I. If the line pressure is more than the maximum supply
pressure, then use a line regulator which corresponds to the supply pressure.
5.7.
After gas connections have been made, make sure the heater and all gas outlets are
turned off before the main gas supply is turned on. Turn the gas pressure on and check for
leaks. To check for leaks, apply a solution of soap suds to all connections and joints
or check by one of the methods listed in Appendix D of ANSI Z223.1/NFPA 54 (latest edition) Natural
Fuel Gas Code. DO NOT USE AN OPEN FLAME OF ANY KIND TO TEST FOR LEAKS.
SECTION 6: INSTRUCTIONS FOR PRESSURE TEST GAUGE CONNECTION
6.1.
Supply Pressure: Installer to provide a 1/8"
N.P.T. plugged tapping, accessible for test gauge connection immediately
upstream of the gas supply connection to the heater.
6.2.
Manifold Pressure: Turn gas valve to "OFF" position. Remove 1/8" plug from manifold
downstream from the valve and connect 1/8" nipple to the tapped hole. Connect gauge to nipple.
Turn on the gas supply.
6.3. With the main burner operating, check burner manifold pressure using a water manometer (see Table
4 on page 6 for correct setting pressures). If
adjustment is required, remove cover screw of the appliance regulator .
Using a small screwdriver, turn adjustment screw clockwise
to decrease pressure to burner. Replace cover screw.
6.4. Gauges which measure in pounds per square inch or
ounces per square inch are not accurate enough to measure or set
the manifold pressure. Use a water manometer.
