Pellet Fuel
General Information
7
Using the UltraGrate burn system, the Whitfield Quest Plus has been designed to burn wood residue pel-
lets with up to 3% ash content. Agricultural pellets
(i.e
...
Corn, alfalfa etc.) are not permitted to be burned
in the stove. Dirty fuel will adversely affect the performance of the stove.
Caution: The use of unapproved, dirty, wet and/or high salt content fuel will void the warranty!
Wood pellets manufactured to the Pellet Fuels Institute (P.F.I.) Certification Standard are available in two
grades, Standard and Premium. The primary difference between the two
is
the ash content of the pellets.
The
P.F.I.,
specification for Standard Grade
&
Premium Grade residential pellet fuel is as follows:
CHLORIDES (Salt): Less than 300
p.p.m..
BULK DENSITY: 40 ib.
1
cu. ft. minimum
MOISTURE CONTENT:
8%
maximum
ASH CONTENT:
<
3% maximum (Standard Grade)
<
1%
maximum (Premium Grade)
FINES: 0.5% maximum through a
118
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), but adversely
affects the performance of the stove by blocking off the air passages in the grate. Even 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 Maintenance for more informa-
tion on cleaning.
Ash
The frequency of removal of the ash and maintenance performed on the stove
is
directly proportional to
the ash content of the fuel and the operation duration of your Whitfield Stove. Low ash fuel may allow
longer intervals between cleaning, however, a stove burning high ash fuel may need to be cleaned as often
as 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.
Fuel Feed Rates
Different brands of pellets will feed at varying rates due to their size and density (length and diameter). This
may require a slight adjustment in the damper control or the pellet feed control to compensate. See
