H*38DF PFC Peninsula Gas Fireplace

Installation

 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�

 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: Installing the Gas Line

We recommend careful consideration be given to the effects of elevated mantel

temperatures which may be in excess of product design, for example: candles, plastic

or pictures. This can cause melting, deformation, discoloration or premature failure of

T.V. radio, and other electronic components.

CAUTION

When pressure testing the fireplace, Gas line, and input system follow the appropriate

local codes or your area. DO NOT connect the fireplace to pressures in excess of

1/2lb. This will damage the gas control valve.

NOTICE

Note: Images are shown without screens for clarity purposes. However,

your replace should not be operated without proper installation of

screens.

WARNING:

An inspection of the explosion relief appers and door

MUST be made prior to lighting the replace. A faulty seal

on the door gasket and/or explosion ports will result in

products of combustion leaking into the living space and

may result in carbon monoxide poisoning.

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.

 Conversion kits must be installed by a qualied service technician.

Section 5-2: GAS PRESSURE

 See Figure 21 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 5-3: GAS CONNECTION

WARNING

When installing the replace - gas lines, ttings,

accessories or any other objects cannot impede the

proper movement of the door buckles.
