undue triggering of the detector when reloading.

• Do not unplug the stove if you suspect a malfunction.

Turn the ON/OFF SWITCH to ”OFF’ and contact your

dealer.

• Your stove requires periodic maintenance and

cleaning (see ”Maintenance”). Failure to maintain

your stove may lead to improper and/or unsafe

operation.

• Disconnect the power cord before performing any

technician.

• Do not operate your stove with the viewing door

open. The auger will not feed pellets under these

circumstances and a safety concern may arise from

sparks or fumes entering the room.

Your pellet stove has been approved for installation in the USA and Canada. It may also be installed in a

manufactured or mobile home. Your stove is Certied to ASTM E1509-12 (2017)and Certied to ULC S627-00. This

manual describes the installation and operation of the U.S. Stove, 5501S wood heater. This heater meets the 2020

U.S. Environmental Protection Agency’s crib wood emission limits for wood heaters sold after May 15, 2020. Under

specic test conditions this heater has been shown to deliver heat at rates ranging from 13,281 to 27,492 Btu/hr.

This heater achieved a particulate emissions rate of 1.0 g/hr when tested to method ASTM E2779-10 (*and an

efciency of 69%).

* Pellet size may effect the actual rate of fuel feed and burn times. Fuel feed rates may vary by as much as 20%.

on a non-combustible oor surface in compliance with

clearance requirements for a freestanding stove installation.

Your pellet stove may be installed to code in either a

conventional or mobile home (see “Special Mobile Home

Requirements”). It is recommended that only a authorized

technician install your pellet stove, preferably an NFI

certied specialist. DO NOT CONNECT THIS UNIT TO ANY AIR

DISTRIBUTION DUCT OR SYSTEM. The use of other components

other than stated herein could cause bodily harm, heater

damage, and void your warranty.

Termination in one of these areas can also lead to unpredictable pressure situations with the appliance, and

could result in improper performance and/or malfunction. The termination must exhaust above the outside air

inlet elevation. The termination must not be located where it will become plugged by snow or other materials. Do

not terminate the venting into an existing steel or masonry chimney.

B. Minimum 1-foot (0.3m) clearance above any

door or window that opens.

C. Minimum 3-foot (0.91m) clearance from any

adjacent building.

D. Minimum 7-foot (2.13m) clearance from any

grade when adjacent to public walkways.

F. Minimum 3-foot (0.91m) clearance from an forced

air intake of any appliance.

I. Must be a minimum of 3 foot (0.91m) above the

roof and 2 foot (0.61m) above the highest point or

the roof within 10 feet (3.05m).

Canadian installations must conform to CAN/CSA-B365. To vent the

unit through the wall, connect the pipe adapter to the exhaust motor

adapter. If the exhaust adapter is at least 18” (457 mm) above ground

level, a straight section of pellet vent pipe can be used through

the wall. Your heater dealer should be able to provide you with a

with a horizontal cap, which would complete the installation. A

support bracket should be placed just below the termination cap or

one every 4ft (1.22m) to make the system more stable. If you live in an

area that has heavy snowfall, it is recommended that the installation

be taller than 3ft (0.91m) to get above the snowdrift line. This same

installation can be used if your heater is below ground level by simply

adding the clean-out section and vertical pipe inside until ground

level is reached. With this installation you have to be aware of the

snowdrift line, dead grass, and leaves. We recommend a 3ft (0.91m) minimum vertical rise on the inside or outside

of the house. The “through the wall” installation is the least expensive and simplest installation. Never terminate

pipe manufacturer’s directions). It is important to note that if your vertical run of pipe is more than 12ft (3.7m), the

pellet vent pipe size should be increased to 4” (102 mm) in diameter.

Do not exceed more than 4ft (1.22m) of pipe on a horizontal run and use as few elbows as possible. If an offset is

required, it is better to install 45-degree elbows rather than 90-degree elbows.

THE WALL

ATTENTION: DO NOT vent under any porch, deck, awning, or in any semi enclosed or roofed area. Doing so

may result in unpredictable airow at the vent cap under certain conditions and can affect the performance

of your stove, as well as, other unforeseeable issues.

• This stove must be securely fastened to the oor of the mobile

home through the two holes in the rear of the stove using 2, 1/4”

lag bolts that are long enough to go through both a hearth

pad, if used, and the oor of the home.

• The heater must be electrically grounded to the steel chassis

of the mobile home with 8 GA copper wire using a serrated or

star washer to penetrate paint or protective coating to ensure

grounding.

• Vent must be 3 or 4-inch “PL” Vent and must extend a minimum

or 36” (914 mm) above the roof line of the mobile home and must be installed using a certied ceiling re stop

Depending on your location and home construction, outside air may be necessary for optimal performance.

1. With the stove in the operating position, mark and drill a hole to accommodate the 2” exible hose.

2. Insert the hose through the wall and attach the Outside Cover with one of the 2” hose clamps provided.

3. Then attach the Outside Cover to the outside wall.

4. Next, attach the Rodent Cover to the Outside Cover using four (4) of the #10 x 3/4 screws supplied.

5. On the inside of the home, slide the Inside Plate over the tube then attach to the wall with the four drywall

as shown.

8. Stretch the 2” ex hose to the air inlet on the back of the stove. Attach using the other 2” hose clamp. The

hose will extend up to 4 feet in length.
