NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE
If conditions 1, 2 or 3 occur, the refractory
should be replaced. For minor defects, repair as
noted above.
MAINTENANCE GUIDELINES
Your fireplace is designed to operate trouble-
free with minimum maintenance. However, like
any fine appliance, it deserves and requires
some housekeeping attention.
Your fireplace will perform better – and cer-
tainly look more attractive to family and friends
– if it is cleaned before each use. Before the first
seasonal use in Autumn and after the last fire in
Spring, it is important to inspect the fireplace
system carefully. We recommend at least two
complete fireplace inspections a year.
Before Each Use
1. Clean the firebox of excessive ashes. Some
owners prefer to leave a small layer to insulate
the cold refractory below the grate which helps
fire starting.
If your particular model fireplace has a factory
supplied grate attached, it is permissible to
remove the grate for cleaning; however, the
grate must be re-attached to the fireplace be-
fore the next burn.
2. Keep the fireplace screens clean so combus-
tion air flows freely.
3. Spot check the brick-like refractory for small
cracks. Heat from the fire expands it slightly.
When it cools, it contracts.
Twice A Year Check-Up
Normally, twice a year, you should inspect your
fireplace following this list:
1. Inspect the opening in your chimney top and
remove any debris that could clog it. The cap is
usually held in place by four (4) screws, which
remove easily for checking or cleaning the full
length of the flue from above. Remove the
chimney top while wearing gloves to guard
against any sharp metal edges.
2. Inspect the entire flue from the top down for
obstructions such as birds nests, leaves, etc.
This may be done by using a flexible handled
chimney cleaning brush. If the chimney con-
tains offset/return elbows; a soft brush cleaning
from the top down to any elbow and then from
the firebox up to the offset/return section is the
proper method. The beam from a powerful
flashlight will help in this inspection.
LINTEL EXTENSION
These Custom Multi-Open Factory-Built
Fireplaces were designed, tested and listed
with an 18" (457 mm) high viewing area, floor
to lintel. However, varying conditions such as
altitude, climate, wood type, moisture content
of fuel, dwelling design peculiarities, average
ambient air pressure and humidity may effect
the performance of this fireplace. If an unac-
ceptable amount of smoking occurs while the
doors are open, the adjustable lintel can be
moved to correct the smoking condition.
The lintel extension can be lowered a maxi-
mum of 2" (51 mm) using a predrilled hole
located at the top of the lintel extension. To
lower the lintel extension 1" (25 mm), drill a
1/8" (3 mm) hole where the dimple is located.
(See
Figure 7.)
To lower the lintel extension on Model CST-38,
remove the two screws from both ends of the
lintel extension (located behind the screen
assembly). Slide the lintel extension down and
align the desired holes in the lintel extension
with the holes in the lintel frame. Reattach
using the screws previously removed. Repeat
this procedure for the lintel extension on the
opposite side of the fireplace. (
Figure 7 )
1. Remove the two (2) screws from one of the
side lintel extension, leaving the lintel extension
on the other side attached to the lintel frame.
Only lower the end of the lintel extension closest
to the closed end (refractory wall) of the CPF-
38. Aligning the desired holes in the lintel
extension with the holes in the lintel frame and
reattach using one (1) of the screws previously
removed.
2. Remove the two (2) screws from the lintel
extension on the other side of the fireplace.
Lower the whole lintel extension to the desired
holes and reattach using the screws just re-
moved.
3. On the lintel extension first lowered, realign
the holes as necessary then insert and tighten
the remaining screw.
REFRACTORIES
All fireboxes contain a furnace refractory floor.
Some models also have refractory sides and
backs. These refractories are reinforced with
steel, but can be broken by improper use. Drop-
ping logs on the bottom refractory and building
fires directly against the refractories can cause
premature burnout of these components. It
may easily be repaired or replaced at costs far
below repair and maintenance for masonry fire-
places.
Proper care and “burn-in” of the firebox will
prolong the period of enjoyment without exten-
sive maintenance. For the first few uses, build
small fires – not roaring infernos. The materials
used in the refractories contain and absorb
moisture. It is important to “cure” the refracto-
ries by building only modest fires.
Under normal usage, it is expected that hairline
cracks will appear in the refractory surface.
These hairline cracks do not affect the safe
operation of the fireplace.
Refractories should be replaced when:
1. The crack opens more than 1/4" (19 mm).
2. Pitting in the surface is extensive and pits
become deeper than 3/16" (4.76 mm).
3. Any piece of refractory larger than 2" (51 mm)
in radius and 3/16" deep becomes dislodged.
If your refractory has a crack less than 1/4"
(19 mm) in width, a simple Refractory Patch
Kit, Model RPK, can easily be used to fill the
crack and repair the refractory.
Figure 7
On Model CPF-38 the two (2) side lintel exten-
sions are welded to the end lintel extension. The
lintel extension lowers similarly to the CST-38
lintel extension. However, to prevent the end
lintel extension from being misshaped, follow
the following steps while referring to
Figure 7.
