EP8-5 Modular Series Fireplace
Installing The Gas Line
The gas line must be installed before finishing the 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 in-
let 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.
• 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 shutoff 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 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).
Notes:
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 detec-
tion 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 EP28 Series' gas valve, located behind the lower trim, may be
connected to a wall switch. The valve generates its own power. This is
a millivolt circuit. Use only low voltage wire, and Do Not connect any
external power to it.
Refer to Figure 24a, 24b, and 24c for wiring requirements.
Note: The switch location must not exceed 30' from the fireplace.
B-Vent Installation
The EP-28 Modular Series is certified for use with standard 5"
B-Vent and requires no B-Vent appliance connector. Simply attach
the B-Vent to the fireplace flue collar, and secure it to the L-shaped
brackets on each side of the opening 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
CAUTION:
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 fifteen (15) minute
warm up period. The manufacturer will not be responsible for
any installations with inadequate draw.
