King KP5522-W Pellet Stove FAQ

What type of pellets should I use in the King KP5522-W?

US Stove recommends using only PFI (Pellet Fuels Institute) certified premium hardwood pellets. The stove is designed and tested specifically for wood pellets — burning corn, coffee pellets, or other alternative fuels is not permitted and will void the warranty.

Can the KP5522-W be installed in a mobile home?

Yes. The KP5522-W is USA mobile home approved when installed with the optional 69FAK Fresh Air Kit, which is required for mobile home installations. A fresh air kit is also recommended for newer, tightly sealed homes or any installation where makeup air is limited.

How does the Wi-Fi functionality work and what's the difference between the "W" model and the standard version?

The "W" designation indicates Wi-Fi capability, allowing you to control and monitor the stove using the US Stove Co. app on iOS or Android devices. The non-W model includes a wireless remote control that works with an infrared sensor on the stove instead of app-based control.

What venting is required for the KP5522-W and can it exhaust through the ceiling?

The stove uses a negative draft system requiring listed 3" or 4" "PL" pellet vent pipe. Yes, ceiling exhaust is supported — refer to the owner's manual for specific installation recommendations. Installation must include at least 3 feet of vertical pipe outside the home, with a maximum recommended vertical vent height of 12 feet for 3" PL vent.

Can I use a smart or wireless thermostat with this pellet stove?

No. The control board only accepts wired thermostats and is not compatible with wireless or smart thermostats. Additionally, the stove operates in High/Low T-Stat mode rather than On/Off — it will continue running at the lowest setting even when the set temperature is reached.

What kind of backup power do I need during an outage?

US Stove recommends a minimum 1000W pure sine wave inverter battery backup for short-term outages. If using a generator, a 1000W inverter generator is recommended to safely run the stove's electronic components and combustion blower.

How often does the KP5522-W need to be cleaned and maintained?

The burn pot should be emptied and cleaned before each ignition, and inspected daily during continuous use. The chimney connector and venting should be inspected annually (or every ton of pellets burned) by a qualified technician to check for soot, fly ash, or creosote buildup.

Does the King KP5522-W qualify for the federal energy tax credit?

Yes. With 76% efficiency, the KP5522-W exceeds the 75% efficiency threshold required to qualify for the 30% IRS 25C Residential Energy Tax Credit. This credit can offset a significant portion of the purchase and installation cost — consult your tax professional for eligibility specifics.
