GENERAL INFORMATION
The Whitfield Quest, with its UltraGrate burn system, has been designed to burn wood residue
pellets with up to 3% ash content. Only Pellet Fuel Institute (P.F.I.) approved fuels should be
used in this stove. Wood Pellets manufactured to the P.F.I. Certification Standards are available
in two grades: STANDARD and PREMIUM. The premium grade pellets have a lower ash con-
tent than the standard grade. The P.F.I. specification for standard and premium grade residential
pellet fuel follows:
CHLORIDES (Salt):
Less than 300 p.p.m.
BULK DENSITY:
40 lb./ cu. ft. minimum
MOISTURE CONTENT: 8% maximum
ASH CONTENT:
3% maximum(Standard Grade)
1% maximum (Premium Grade)
FINES:
0.5% maximum through a 1/8” screen
CLINKERING
Silica (or sand) in the fuel, along with other impurities, can cause clinkering. A clinker is a hard
mass of silica formed in the burning process. Clinkering is a function of the fuel (not the stove),
and adversely affects the performance of the stove by blocking off the air passages in the grate.
Even a P.F.I. approved pellet fuel may tend to clinker. A clinker can be removed from the burn
grate and placed in the ash pan with the use of the grate scraper/ash pan tool furnished with
your stove. See Routine Cleaning & Maintenance for more information.
ASH
The frequency of ash removal and other maintenance performed on the stove is directly propor-
tional to the ash content of the fuel and how frequently you use your Whitfield stove. Low ash
fuel may allow longer intervals between cleaning, however, a stove burning high ash fuel may
need to be cleaned everyday.
PLEASE NOTE: Pyro Industries, Inc., has no control over the manufacturing of pellet fuel and
will not be held responsible for poor stove performance or any damage caused by inferior pellet
fuels.
