A gas detecting warning system is the only reliable way
to detect a propane gas leak. Rust can reduce the level
of odorant in propane gas. Do not rely on your sense
of smell. Contact a local propane gas supplier about
installing a gas detecting warning system. If the presence
of gas is suspected, follow the instructions listed in the
Safety Considerations section of this manual.
All propane gas equipment must conform to the safety
standards of the National Board of Fire Underwriters,
NBFU Manual 58.
CANADA: National Standard of Canada, Natural Gas and
Propane Installation Code (NSCNGPIC) CAN/CSA B149.1-
15.
For satisfactory operation, propane gas pressure must be
10” WC at the furnace manifold with all gas appli ances in
operation. Maintaining proper gas pressure depends on
three main factors:
1. Vaporization rate, depending on temperature of the
liquid, and “wetted surface” area of the con tainer or
containers.
2. Proper pressure regulation. (Two-stage regulation is
recommended for both cost and efficiency).
3. Pressure drop in lines between regulators, and
between second stage regulator and the appliance.
Pipe size will depend on length of pipe run and total
load of all appliances.

Disconnect this unit and shutoff valve from the gas supply
piping system before pressure testing the supply piping
system with pressures in excess of 1/2 psig (3.48 kPa).
Isolate this unit from the gas supply piping system by
closing its external manual gas shutoff valve before
pressure testing supply piping system with test pressures
equal to or less than 1/2 psig (3.48 kPA).
