Installation

Important: Corner Installation is available only for

Top Vent Units.

Figure 18. Reducing Vertical Vent from 5/8" to 4/7".

Reduced Vertical Installation

It is possible to reduce vertical vent runs from 5"/8" venting to 4"/7"

venting. Reduced vertical venting may only be used when the installation

exceeds 12 feet and terminates through the roof, and if the vertical vent

reducer is used with the following venting conguration.

Figure 20. Corner installation.

Figure 21. Flex installation.

2. 45° Corner Installation.

Attach an PEL-90 (90° elbow) directly onto the ue collar, and attach

it to the PEL-45 (45° elbow). Cut the PXT-18 to suit and insert it into

the PEL-45. Slide the replace into position, and then connect it to

the exterior termination.

3. Corner Installation — 45° or less.

Use an PTO-3 termination and an PFL-1 or PFL-2 (12" or 24"

compressed length) and a frame, if appropriate. Flex may be turned to

obtain desired degree of angle required but must not exceed 45°.

B. Multi-Elbow Installations

For more difcult installation situations, the L52-DF Rear Vent must be

installed with only one or two 90° elbows. If using either of these installation

options, you must adhere to MIN, two of the following guidelines:

 One 90° elbow must be placed directly on the ue collar; then travel

vertical, vent through the roof to termination.

 Or, you must use two 90° elbows; have a minimum vertical lift of 50"

(measured from the hearth) As shown in Figure 23.

 IMPORTANT: For both Rear-Elbow installations your vent run must

fall within the limits set by the Graph, Figure 22c

Before you install any venting, you must determine whether the venting

run will be acceptable. Unacceptable venting can affect the replace's

combustion.

The Venting Graph

Measure the vertical height from the replace hearth to the centre of

the termination and the horizontal run from the from the replace ue

collar to the wall ange of the termination. Plot on the Venting Graph

(Fig. 22c) with an 'X'.

Example A: (Acceptable Installation)

If the vertical dimension from the hearth is 84" and the horizontal

run to the wall ange of the vent termination is 36", this would be

an acceptable installation.

Example B: (Acceptable Installation)

If the vertical dimension from the hearth is 108" and the horizontal

run to the wall ange of the vent termination is 120", this would be

an acceptable installation.

Example C: (Unacceptable Installation)

If the vertical dimension from the oor of the replace is 72" and

the horizontal run to the wall ange of the vent termination is 84",

this would NOT be an acceptable installation.
