These fireplace models are vented gas fireplaces that use a millivolt
gas control valve with a millivolt ignition system. P325/VP325
models have a 5" B-vent and P324/VP324 models have a 4" B-vent.
A properly sized B-Type venting system and listed type vent cap are
not supplied but are required for proper operation. See venting
instructions on pages 8 and 9.
INTRODUCTION
These models are factory equipped for use with natural gas and must
be converted when intended for use with propane/LP gas. Conversion
kits PCBM-324 and PCBM-325 may be purchased for simple
conversion to propane/LP gas. See Accessories, page 29.

The appliance must be isolated from the gas supply piping system
by closing its individual manual shutoff valve during any pressure
testing of the gas supply piping system at test pressures equal to or
less than 1/2 psig (3.5 kPa).
For the purpose of input adjustment two pressure taps (for IN and
OUT pressures) are provided on the gas control valve for test gauge
connections to the appliance.
The installation must conform with local codes or, in the absence of
local codes, with the current National Fuel Gas Code, ANSI Z223.1
