Draft Test Procedure
After the venting is completed, the rebox low draft
will need to be checked and possibly adjusted. After
removing the 3/8” bolt from the draft hole shown in Fig.
9, insert the draft meter tube. The appliance doors and
hopper lid must be latched during this test. (It is recom-
mended that the draft meter have a scale of 0 to 1” WC.)
Turn the feed adjuster to “Test”. this will start the
combustion blower and allow you to check and record
the High Draft ______ - IWC date _______ The
maximum draft must not exceed -.85” W.C. Some form
of vent restrictor may be needed. (There is no control
board adjustment for the High Draft)
After the rst 60 seconds the “Test” mode lowers the
combustion blower voltage to the Low Burn voltage.
During this lowered voltage cycle the Low Burn Draft
must be checked and adjusted if necessary. The recom-
mended low draft setting should be between -.25 & -.35
IWC. Depending on the amount of vertical rise, it may
not be possible to get a low draft reading in this range.
In this case, a maximum low draft of -.55 is acceptable.
The adjustment screw is through the small hole to the
right of the Igniter Light. See Fig. 10. Adjusted Low
Draft is __________ -IWC.
Don’t forget to turn the feed adjuster off of “Test”.
Do not operate if the high draft exceeds -.85” W.C.
Excessive draft readings may be due to restriction in
the combustion air supply. Check for obstructions.
The Control
The boiler has the option to have the control panel
covered or un-covered See Fig. 11. There is a pair of
slots provided for each position. Simply move the cover
to the desired position by placing the tabs on the cover
in the proper slots.
WARNING: Do not operate with the hopper
lid or re chamber or ash removal doors open.
WARNING: Do not store fuel or other
combustible material within installation
clearance area.
CAUTION: Hot while in operation. Do not
touch. Keep children, clothing, furniture,
and other combustible material out of the
installation clearance area.
