Installation

IMPORTANT MESSAGE: SAVE THESE INSTRUCTIONS

The Prestige Series P52DF* Direct Vent replace must be

installed in accordance with these Instructions. Carefully

read all the Instructions in this manual rst. Consult the

Local Gas Branch to determine the need for a permit prior to

starting the installation. It is the responsibility of the installer

to ensure this replace is installed in compliance with the

manufacturers instructions and all applicable codes.

BEFORE YOU START:

Installation Checklist

Determine the desired install location of your replace.

See Section 1, Dimensions on Page 5, and refer to

the Framing Section 2 for details.

Select the location of your termination and resulting

vent run.

Your selected termination location must be the

highest point in the Direct Vent installation.

Should it be impossible to meet the venting

requirements laid out in Section 4: Venting, please

contact a local Montigo dealer regarding the use of

a Montigo Power Vent.

Lay out the Vent run; calculating the required elbows

and straight runs of 5"/10" (5"/8" if applicable) flex

or rigid pipe.

Layout Electrical Requirements Refer to Section 5:

Wiring, for Details.

Refer to Section 6: Installing the Gas Line, for details

on the gas connection and access.

Refer to local codes and guidelines for installation

requirements.

Installation and repairs should be done by a

qualied contractor and must conform to:

• Installations in Canada must conform to the local

codes or in the absence of local codes to the current version

of Natural Gas and Propane Installation Code, CSA B149.

Electrical Installations must conform to the local codes or,

in the absence of local codes, to the current version of

Canadian Electrical Code, CSA C22.1.1

• Installations in the USA must conform to the local

codes or in the absence of local codes to the current

following guidelines must be adhered to:

For Rear Vent multi-elbow applications, the minimum

clearance is 1" from the elbow off the rear of the replace to

a wall, or any combustible materials, and 12" clearance from

the top of the replace to the underside of any combustible

shelf materials.

For Top Vent applications, the minimum clearance is 1"

from the rear of the replace to a wall, or any combustible

materials, and 26" to the underside of any combustible

shelf materials.

1” clearance is maintained on sides and bottom of vent

runs and 2” above horizontal vent runs to any combustible

material.

Figure 6d. Securing the Nailing Flange Extension.

Installing the Nailing Flange Extension

(Part No. P52087)

The supplied nailing extension must be placed along the top

edge of the replace and securely fastened into place, as

shown in gure 6d. Note: The nailing ange extension can

be substituted with a piece of NON-Combustible material

of the same size and thermal characteristics, ie: cement

board or equivalent.



Before installing the supplied nailing ange extension, fold

tabs at bottom of nailing ange to a 90 degree angle.

To avoid elevated mantel temperatures, all P52DF* gas

replaces are required to have the supplied standoffs installed.

The replace is supplied with two standoffs. Bend and install

these standoffs on top of the replace ensuring that the

height of the standoff maintains a 7 ½" clearance.

Section 3-1: CONVERTING TO REAR VENT

Use the following instructions to convert a P52DF* for Rear

Vent use:

1. Remove the Rear ue cover and gasket (5" and 10")

on the ue outlet, as shown in Figure 9.

2. Next, Remove the Top ue collar's (5" and 10") on the

ue outlet, as shown in Figure 9

3. Install the (removed) Rear ue cover and gasket

material, to the Top vent outlet. Fasten the cover with

included hardware, as illustrated Figure 10.

4. Install the (5" and 10") collars to the rear vent outlet

using the included hardware, as illustrated Figure 10.

Montigo supplies a variety of direct venting and termination

options. The direct vent termination location MUST be

selected such that it is the highest point in the venting

assembly. It should also be selected such that it provides

the shortest vent run possible. Should it be impossible to

ensure that the termination is the highest point or to meet

the venting guidelines laid out below please contact your

Montigo dealer to discuss power venting options.

NOTES FOR PLANNING VENTING:

Venting can originate from the unit through the top or

through the rear

Venting can terminate through the roof or through an

exterior wall.

Refer to Appendix A - Termination Locations to ensure

the planned termination location is acceptable.

Once the termination location has been established,

refer to the appropriate section below for installation

details

All replaces shipped from the factory are Top vent

with 5" and 10" collar installed.

UNITS CANNOT BE REAR VENTED

The maximum termination point is 32’ above the replace

(NOTE: if the maximum termination height is used, the

ame pattern may be affected).

The Vertical termination must be a minimum 2’ higher than

where the termination exits the roong materials, (asphalt

shingles, cedar shakes, etc). This distance should be

measured from the high side of the roof slope where the

ue ashing intersects the roong materials. (see Figures

8 to 8c).

Termination location must be a minimum 6’ from a

mechanical air inlet.

Termination location must be a minimum 18” from a

parapet wall.

For a more detailed diagram of allowed termination

locations, see Appendix A.

A maximum of two offsets (each offset is made up of 2-90°

bends) may be made.

Firestops must be installed as required by National &

local codes

Ensure all runs are supported with a minimum of 3 supports

per 10’ of venting.
