3.4.3 Gas Pressure Requirements and Checking
Two pressure taps for checking input and output gas pressures are located on the main gas valve. A qualified installer should use
this fitting for setting the correct gas pressure during initial installation.
The appliance and its appliance main gas valve
must be disconnected from the gas supply
piping system during any pressure testing of
that system at test pressures in excess of 1/2
psi (3.5 kPa).
The appliance must be isolated from the gas
supply piping system by closing its equipment
shut-off valve during any pressure testing of
the gas supply piping system at test pressures
equal to or less than 1/2 psi (3.5 kPa).
If the factory-built fireplace has no gas access hole(s)
provided, an access hole 1.5” or less may be drilled
through the lower sides or bottom of the firebox in a
proper workmanship like manner. This access hole
must be plugged with non- combustible insulation after
the gas supply line has been installed.
3.4.4 Drip Leg Requirement
A drip leg/ sediment trap must be installed within the main gas supply line serving this appliance.

floor-mounted manual gas shutoff valve approved per local gas plumbing codes
and install per local gas plumbing codes in the specified location. Local
requirements supersede all other codes.
