Installing The Gas Line
The gas line must be installed before finishing the ME34-BV Fire-
place. 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 brass 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.
Installation
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.
Installing The Remote Switch
The ME34-BV's gas valve, located behind the lower brass trim, may
be connected to a wall switch. The valve generates its own power on
a millivolt circuit.
Use only low voltage wire, and DO NOT connect
any external power to it.
Refer to Figure 12 for wiring requirements.
Note: The switch location must not exceed 30' from the fireplace.
Figure 4. Gas line access.
During any pressure testing of the gas supply piping that excedes 1/2
psig (3.5 kPa), the appliance and its individual shutoff valve must be
disconnected from gas supply system.
When pressure testing the gas supply piping system at test pressures
of
less than or equal to 1/2 psig (3.5 kPa), the appliance must be
isolated from the gas supply piping system by closing its individual
manual shutoff valve.
B-Vent Installation
The ME34-BV 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.
Do not penetrate the inner sleave of the B-Vent when tightening the
screws.
Refer to the current CAN/CGA B-149.1 and .2 or ANSI Z223.1-1988
Gas Installation Code for specific vent sizing.
n Test your B-Vent installation after completion to ensure that
no combustible by-products are spilling from the fireplace
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.
