H-Series BF Gas Fireplace
Installing The Gas Line
The gas line must be installed before finishing the H-Series BF Fireplace.
Natural Gas requires a minimum inlet gas supply pressure of 5.5" W.C.
& a manifold pressure of 3.5" W.C. Propane Gas requires a minimum
inlet gas supply pressure of 11" W.C. & a manifold pressure of 10" W.C.
Provision must also be made for a 1/8" N.P.T. plugged tapping and be
accessible for test gauge connection immediately upstream of the gas
supply controls to the appliance. The fireplace gas connection and
the main operating gas valve is located behind the removable trim at
the bottom of the unit and need only be attached to the gas line with
an approved fitting, as required by the applicable installation codes.
To access the fireplace gas connection the main burner must be
removed as shown below in figure 4b.
• Only use gas shut-off valves approved for use by the state, province,
region, or governing body, in which the appliance is being installed, or
as required by the applicable installation codes.
• Flexible gas connectors must not exceed 3 feet in length, unless it is
allowable within applicable installation codes.

The appliance and its individual shut-off 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 psig (3.5 kPa).
The appliance must be isolated from the gas supply piping system by
closing its individual manual shut-off 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).
Note: After gas line is connected, each appliance connection,
valve and valve train must be checked while under normal
operating pressure with either a liquid solution, or leak
detection device, to locate any source of leak. Tighten any
areas where bubbling appears or leak is detected until
bubbling stops completely or leak is no longer detected.
DO NOT use a flame of any kind to test for leaks.

Installation
The H-Series BF is certified for use with standard 4" B-Vent and requires
no B-Vent appliance connector. Simply attach the B-Vent to the fireplace
flue collar, and secure it using 1/4" sheet metal screws.
Refer to the current CAN/CGA B-149.1 and .2 or ANSI Z223.1-1998
Gas Installation Code for specific vent sizing.
Gasline Access
To avoid elevated mantel temperatures, all H-Series BF gas
0.875" dia.
fireplaces are required to have the supplied standoffs installed.
The fireplace is supplied with two standoffs. Bend and install these
standoffs on top of the fireplace ensuring that the height of the standoff
maintains a 6" clearance.
Figure 5. Installing the standoff's.
Once the fireplace is placed into the framed opening, the supplied
nailing extension must be placed along the top edge of the fireplace,
and nailed in place to the framing, as illustrated below.

Vent Installation

Note:
If more than 12 feet of B-Vent is used on the vent
runs, use ceiling supports.
Cautions:
Test your B-Vent installation after completion to ensure that
no combustible by products are spilling from the fireplaces
opening. This draft test should be performed after a three(3)
minute warm up period. The manufacturer will not be
responsible for any installations with inadequate draw.
Note:
Due to the top vent clearances to combustible
materials there is no available shelf installation for
the H-Series BF fireplaces.
