Gas Line Requirements; Fuel; Gas Line Connection; Gas Inlet Pressure - Lopi Pro Builder 72 Linear GSB2 Installation Manual

Gas Line Requirements


The gas line must be installed in accordance with all local codes and the requirements listed below.
In the absence of local codes, follow ANSI 223.1 in US/Canada or AS/NZS 5601.1 in Australia.

The fireplace and gas control valve must be disconnected from the gas supply piping during any
pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPA). For pressures under
1/2 psig (3.5 kPA), isolate the gas supply piping by closing the manual shutoff valve.

Leak test all gas line joints and the gas control valve prior to and after starting the fireplace.

This unit has been listed using the included internal gas shutoff valve.

Fuel


This fireplace is designed either for natural gas or for propane (but not for both).

Gas Line Connection


Installation must be performed by a qualified installer, service agency or the gas supplier (In Massachusetts a
licensed plumber/gasfitter).

Gas Inlet Pressure

Gas Pressure
Natural Gas
Propane

If the pressure is not sufficient, make sure the piping used is large enough, the supply regulator is
adequately adjusted, and the total gas load for the residence does not exceed the amount supplied.

The supply regulator (the regulator that attaches directly to the residence inlet or to the propane tank)
should supply gas at the suggested input pressure listed above. Contact the local gas supplier if the
regulator is at an improper pressure.
