M38DV-PFC Peninsula Gas Fireplace
Installing The Gas Line
The gas line must be installed before finishing the M38DV-PFC 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
.
* 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
M38DV-PFC
is equipped with a remote-operated valve for use
with a wall switch. See Figure 19 for information on wiring the switch.
The valve is pre-wired and generates its own power.
DO NOT con-
nect any external power to it.
Note:
The switch location must not exceed 30' from the fireplace.

Gas line access.
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).
Installation
Vent Installation
This section covers the installation of direct venting and terminations.
For a detailed diagram of allowed termination locations, see
Appen-
dix B.
Installation Requirements
The M38DV-PFC fireplace uses Premium venting components
with:
5" inner dia. /8" outer dia.
Minimum
2" clearance to combustibles
required for vent pipes
Use only
certified Montigo vent components.
(Use of other parts
will void the Montigo warranty, and may impede the operation of
the fireplace.)
All joints must be secured with a minimum of two screws per joint
Vent terminations must not be recessed in walls or siding
Horizontal runs must be supported by a minimum of two supports
per horizontal run. A minimum of one screw on each side of sup-
port is also required
Flex vent sections may be stretched up to 50% of their total length
(eg. a 24" section may be stretched to 36")
Solid vent sections may be cut less than half way from the tapered
end
Vent terminations can be very hot. If the termination is less than
7 feet above a public walkway, it should be fitted with a certified
Montigo Heat Guard. (Part no. PTKOG)
Do not obstruct, or attempt to conceal, the vent termination.
These actions will affect the operation of the fireplace, and may
be hazardous.
In heavy snow areas, take extra care to prevent snow buildup
from obstructing the vent termination.
Use Montigo VSS Vinyl Heat Shield when using on
applications with vinyl siding to guard against possible
damage.

Installing Terminations with Built-In Frames
Vent Terminations
1. Frame the termination opening to 11" x 11".
2. Fasten the termination to the studs using a minimum of 4
screws.
