Each patio heater is set and tested at the factory for the type of gas supply to be used. Identify
the type of gas, either natural gas or LP gas and make sure that the marking on the nameplate (rating
plate) matches the gas being supplied to the heater. The nameplate is located behind the component
compartment access door.
1. CODE REQUIREMENTS
a)
Installation must be in accordance with local codes, or in the absence of local codes, with the
latest edition of the National Fuel Gas Code, ANSI Z224 and National Electrical Code ANSI/NFPA
70, and for Canada, the latest edition of CAN/CGA-B149.1 and B149.2 and Canadian Electrical Code,
CSA C22.1 Part 1 and Part 2.
o Heaters to be installed in Aircraft hangars must be installed in accordance with American
National Standards for Aircraft Hangars, ANSI/NFPA No. 409.
o Heaters to be installed in Public Garages must be installed in accordance with NFPA No. 88A,
Standards for Parking Structures.
o Heaters must be installed so that minimum clearances marked on the heaters will be
maintained from vehicles parked below the heater.

2. GAS SUPPLY
It is important that the inlet gas piping system be adequately sized for the heater
(s)
it serves. The
gas inlet and manifold pressure required for the heater is listed below. For gas supply line pressures in
excess of ½ psig, consult with your representative or the factory.
Gas Inlet Pressure
Nat Gas
Propane
Maximum Pressure
10” W.C.
13” W.C.
Minimum Pressure
6” W.C.
11” W.C.
Manifold Pressure
5” W.C.
