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, 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.
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.
