INSTALLATION USING A PROPANE SUPPLY TANK
1 When installing the heater for use with propane gas, set the gas selector valve to "Propane"
and lock in position.
2 Arrange the propane supply system to provide for vapour withdrawal from the operating
container. Supplying liquid propane to the heater is dangerous and will damage the
components. Another regulator must be installed on the heater to reduce the pressure
from this regulator to a maximum inlet pressure of 1/2 psi (3.45 kPa).
3 Ensure that for the surrounding temperature the size and capacity of the propane supply
container is adequate to provide the rated Btu/h input to the heater.
4 Turn off the propane supply valve at the container when the heater is not in use.
5 The installation must conform with local codes, or in the absence of local codes, with the
Standard for the Storage and Handling of Liquedied Petroleum Gases, ANSI/NFPA 58 or
the Natural Gas and Propane Installation Code CSA-B149.1.
6 When the heater is to be stored indoors the propane container must be disconnected from
the heater and the container moved away and stored in accordance with the above national
standards.
INSTALLATION FOR NATURAL GAS APPLICATIONS
1 When installing the heater for use with natural gas, set the gas selector valve to the "Natural"
position.
2 A regulator must be installed on the heater to ensure that the pressure to the heater does
not exceed 1/2 psi inlet pressure.
3 The installation of this heater to a natural gas supply must conform with all applicable local
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.
