GAS SUPPLY INSTALLATION
INSTRUCTIONS
CONNECTING HEATER TO GAS SUPPLY
WARNING: Depending on local codes and requirements and
the installer's skill level, the sizing and installation of gas
lines required to safely and efficiently supply the heater may
require the assistance of a professional. If in doubt as to
these requirements, discuss the requirements of this manual
with the dealer from whom the heater was purchased and
your gas supplier.
Locate the hose out of pathways where people may trip
over it or out of areas where the hose may be subject to
accidental damage.
Gas Supply Requirements
• See Table 1 for gas supply minimum, maximum, operating, and
manifold pressures for both heater models. Pressures are provided
in inches of W.C. (water column). Also, see heater rating plates
located on the heater.
WARNING: These patio heaters burn natural gas or liquefied
petroleum (propane) gas and they come equipped with
a regulator. The regulator is built into the gas valve. The
maximum inlet pressure to this regulator is 14 in. W.C.. If
gas line pressure exceeds 14 in. W.C., then an additional
regulator must be installed before the heater/regulator to
step down the pressure to a maximum of 14 in. W.C..
Piping Requirements
All piping installed must comply with local codes and ordinances or
with National Fuel Gas Code, ANSI Z223.1 (NFPA 54), whichever takes
precedence. When installing piping, the following requirements must
be taken into consideration:
• Canadian installations must comply with the B149.1.2 Gas Code.
• Use new properly reamed black pipe free from chips.
• Apply a good quality pipe compound to all male threads prior to
assembly. If propane gas is the fuel, ensure that pipe compound is
resistant to propane gas. Do not use Teflon™ tape.
• A sediment trap shall be installed in the line to the gas valve.
• A dedicated shut-off valve for the heater must be installed in the
gas supply line.

Piping Installation

WARNING: The gas hose must be positioned in such a
way that it does not trip people or create other accidental
damages.
While ensuring that all of the above gas supply requirements and
piping requirements are fulfilled, install piping as follows:

gas valve damage, distortion and malfunction.
Install a threaded nipple into the gas valve.
Connect gas piping to nipple installed in the gas valve.
Ensure the building is properly ventilated. Without lighting the
burner of the heater, open the gas supply valve and pressurize the
piping up to the heater's gas valve.
water solution. Do not use a match or other flame for leak
testing. If during leakage check gas is smelled, turn off the
gas supply and ventilate building.
Using a brush, apply a soap and water solution to all connections
and look for bubbles indicating a leak. If a leak is detected,
turn off gas supply and tighten connections. Retest and tighten
connections.
