Fireplace Facing
When selecting the nish material for your replace, it is important to
remember the following: THE LOWER GAS CONTROL PANEL MUST
NOT BE OBSTRUCTED IN ANY WAY - to do so restricts the air supply
for the control compartments and heat exchanger it also prevents
access for servicing controls.
Decorative facing must not extend past the replace opening at all,
because it will interfere with the access to retainers for removal of
glass door.
WARNING!
When this appliance is installed directly on exterior carpeting, tile
or any combustible material other than wood ooring, it must be
installed on a metal or wood panel extending the full width and
depth of the appliance.
When installing this replace as shown in Figure 5, the outer shell is not
to be installed. Follow Figures 4,5 (wall installation) and Figure 3 (MIN
size enclosure for patio or other contemporary installation) to frame
around the replace chassis.
Note: ONLY Non-combustible materials must be used in construction
of the enclosure. (top, bottom and sides). Steel studs in combination
with concrete, rock, or stone nishing materials, are acceptable. See
Figures 3, 4 and 5.

Section 4: Wiring
WARNING!
Montigo Part No. #HSIT07 must be encased in a water-tight
electrical box OR ensure the box is installed in a dry location
and avoid any moisture. If installed outdoors, ensure you also
install a Ground Fault Interrupt per local code.
Installing The Remote Switch
The H38 SVO's gas valve, located behind the lower 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 4 for wiring requirements.
Note: The switch location must not exceed 30' from the replace.

Section 5: Installing the Gas Line
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 ame of any kind to test for leaks.
WARNING!
When pressure testing the replace, Gas line, and input system
follow the appropriate local codes or your area. DO NOT connect
the replace to pressures in excess of 1/2lb. This will damage the
gas control valve.
The manifold outlet pressure is set from the factory to the
appropriate pressure but should be veried.
To check pressures, control valves have a provision to remove
a 1/8” N.PT. plug to be tted with a hose barb.
Montigo requires a service shut off valve be located in an
accessible location to isolate the gas supply.
Only install gas shut-off valves approved for use by the state,
province, or other governing body in which the replace is being
installed.
Section 5-3: GAS CONNECTION
See Figure 5 below for location of gas line access.
Flexible gas connectors must not exceed 3 feet in length, unless
allowable within local regulations.
Connect incoming gas line to the 1/2"or 3/8" gas inlet port.
Purge all air out of gas line.
Check appliance connection, valve and valve train under normal
operating pressure with a commercially available leak check
solution.
DO NOT USE A FLAME OF ANY KIND TO TEST FOR LEAKS.

Section 5-1: FUEL CONVERSION
Verify that your replace is compatible with your available gas
type. (Natural Gas or Propane shown by "N" or "L" in your
model number
If gas type is not compatible, contact your local Montigo
representative to purchase a conversion kit.
Conversion kits must be installed by a qualied service technician.
Section 5-2: GAS PRESSURE
Optimum appliance performance requires proper input pressures.
Gas line sizing requirements will be determined in ANSI Z223.1
National Fuel Gas Code in the USA and CAN/CGA B149 in
Canada.
Pressure requirements are:
Gas Pressure Natural Gas Propane
Minimum inlet pressure 5.5in. w.c. 11in. w.c.
Manifold pressure 3.5in. w.c. 10in. w.c.
