G. Helpful Hints
When operating your Harman
®
P42i-TCPelletInsert,follow
basic safetystandards. Read these instructions carefully
before you attempt to operate the P42i-TC Pellet Insert.
Failure to do so may result in damage to property or personal
injuryandmayvoidtheproductwarranty.
Cleaning Burn Pot: Whenever your stove is not burning, take
the opportunity to scrape the burn pot to remove carbon buildup.
A vacuum cleaner is handy to remove the residue. Be sure the
stove is cold if you use a vacuum.

the burn pot. The carbon will be pushed out by the incoming fuel.
Always wear gloves when scraping the burnpot.
Disposal of Ashes: Ashes should be placed in a steel
container with a tight tting lid. The closed container of
ashesshouldbeplacedonanon-combustibleoororonthe

otherwise locally dispersed, they should be retained in the
closed container until all cinders have thoroughly cooled.

Performance
• Higher ash content requires more frequent maintenance.
• “Premium” grade pellets will produce the highest heat
output.
• Burning pellets longer than 1-1/2 inches (38mm) can
cause inconsistent feeding and/or ignition.
Clinkers

• Trees from dierentareaswillvaryinmineral content.
For this reason, some fuels will produce more clinkers
than others.
Moisture
• Always burn dry fuel. Burning fuel with high moisture
content takes energy to dry and tends to cool the
appliance thus, robbing heat from your home.
• Damp pellet fuel could turn back into sawdust which
