Installing the optional P52i Air Adapter!

[Don2222]

Hello

Even though this fresh air adapter is optional, IHMO it should be mandatory not only the Harman P52i but any fireplace insert, to save pellets and heat and stop uncomfortable drafts created by drawing room air in from the cracks in the house to the burn pot! Here is why?

With an additional 3" liner and chimney top, nice clean fresh air can be drawn into the burn pot using the Harman P52i Air adapter. When this is installed, Roxul (100% Fire Proof Insulation) can be placed on the damper shelf and around the liners to keep warm heated air in the room from escaping up the chimney! ! !

The Roxul R23 insulation on the damper shelf and around the liner is like shutting a big window in the roof that sucks all the heat out in the winter like an air vacuum!

The house will now be warmer even when the stove is Off!

This stove is very big and quite heavy, has anyone carried it up stairs?
Shipping weight is 475 lbs!

Steps
0. Remove stove from frame if old or in our case remove shipping bolt and seperate frome from stove.
1. Remove original Air Intake flange
2. Screw in top and right side self tapping bolts to hold hew air adapter where orig flange was mounted
3. Must create new hole with self tapper on left side
This is not easy since room blower is in the way.
I found two choices here
a. Remove room blower to get self tapper straight on and screw in.
or
b. Drilll pilot hole on angle, the get sel tapper in
4. Drill two new holes to mount top of air adapter with self tapppers. this was staight forward.
5. Mount 3" flange to P53i Frame for flex liner connection using white lytherm gasket supplied.
6. run liner down chimney. (We tied 4" and 3 " liners together and did both at same time!)
Use separate chimney top and make fresh air lower than flue exhaust chimney cap
Screw fresh air liner to air adapter flange using self tappers. I sealed with silicone, but not neccessary.
7. Add Roxul 100% Fire proof insulation to damper shelf and cut around flex liners to save room heat!
8. Slide stove back in frame

It is a little more work when doing the initial install but well worth it!

Also a good update to save more pellets and stop drafting dirty chimney air amd/or warm room air into the burn pot!

Hello

Note how you can angle the Air Flange and the Flue Flange just by loosening the 4 bolts and turning the collar! Just in case you cannot bend the flex liner so it goes straight up.
In our case we made the flex liner go straight up, but still it may be needed for some chimney installations.
