Maintenance
keep your Merrimack Large Insert
Looking New and working Its best
care of the cast Iron Surface
An occasional dusting with a dry rag will keep the
painted cast iron of your Merrimack Large Insert looking
new.
If the paint needs retouching, first allow the surface to
cool completely. Mask glass, trim parts and enamelled
areas. Wire-brush those areas to be painted. Touch-up
with high temperature stove paint available from your
local dealer. Apply the paint sparingly. Two light coats
are better than one heavy one.
care of the porcelain enamel Surface
Use a soft brush as necessary. Do not use water or
other liquids on your Merrimack Large Insert. Finger-
prints usually can be buffed off porcelain enamel with
a dry, soft cloth. If marks remain, allow the Merrimack
Large Insert to cool completely, then buff with a slightly
damp, soft cloth. Dry completely before starting a fire to
avoid streaking.
Never use abrasives or harsh chemical cleaners on
the porcelain enamel finish; the enamel may scratch
and expose the cast iron, which can then stain or
rust. If you must remove spills or stains from porcelain
surfaces, make sure the fire is out and the Merrimack
Large Insert has cooled completely before cleaning.
Use a kitchen appliance cleaner and/or polish specifi-
cally formulated for enamel surfaces. Apply the cleaner
sparingly with a soft cloth, and buff away all traces.
cleaning the glass
The Merrimack Large Insert glass system requires a
minimum amount of cleaning. Most carbon deposits
that accumulate will burn off during hot fires.
Ash residue that accumulates on the glass should be
removed periodically to prevent etching. To clean the
glass, use the following procedure.
•
Be sure the glass is completely cool.
•
Cleaning with water will work in most cases. Use
a glass cleaner especially made for this purpose
only if deposits are specially heavy. (If heavy
deposits are a frequent occurrence, however,
evaluate your operating techniques.) Do not use
abrasive cleaners.
•
Rinse the glass thoroughly.
•
Dry the glass completely.
adjust the Door Latch periodically
The front door of the Merrimack Large Insert should
close securely to prevent accidental opening and
should close tightly to prevent air from leaking into the
fire chamber. The door handle will be positioned verti-
cally when the door is closed.
Over a period of time, the gasket around the door will
compress and the latch may need adjustment. To ad-
just the handle, follow this procedure:
1. Remove and retain the lock nut with a 9/16” wrench.
(Fig. 13)
. Loosen the set screw with a 1/8” Allen wrench.
3. Rotate the pawl 180°. Replace the lock nut. Tighten
the set screw.
4. Additional adjustment can be made by removing the
flat washer. Or any combination of washer removal
and/or pawl rotation.
Test the door seal. Close the door on a dollar bill and
attempt to pull it free. If the bill is freed with little re-
sistance, the gasket isn’t snug enough at that spot.
Continue to make small adjustments until the setting is
right.
If additional adjusting of the latch does not enable the
door to seal sufficiently in one area, try “adjusting” the
gasket in that area. Pack more cement or a smaller
diameter gasket into the channel beneath the gasket so
the main gasket is raised and makes contact with the
door frame. If this procedure doesn’t solve the problem,
replace the gasket. Instructions for gasket replacement
are given later in this section.
