SP28-F2 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 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.
Installation
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
Gas Installation Code for specific vent sizing.

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.
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).

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.
CAUTION:
Notes:
n
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.
