Automatically Fired Boilers, ANSI/ASME CSD-1.
The SlimFit boiler gas manifold and controls met safe light-
ing and other performance criteria when boiler underwent
tests specified in ANSI Z21.13 — latest edition.
Before locating the boiler, check:
1. Check for nearby connection to:
System water piping
Venting connections
Gas supply piping
Electrical power
Location of drain for condensate
2. Check area around boiler. Remove any combustible materials,
gasoline and other flammable liquids.
Failure to keep boiler area clear and free of combustible
materials, gasoline and other flammable liquids and
vapors can result in severe personal injury, death or
substantial property damage.
3. The SlimFit boiler must be installed so that gas control system
components are protected from dripping or spraying water or rain
during operation or service.
4. If new boiler will replace existing boiler, check for and correct
system problems, such as:
System leaks causing oxygen corrosion or heat exchanger cracks
from hard water deposits.
Incorrectly-sized expansion tank.
Lack of freeze protection in boiler water causing system and
boiler to freeze and leak.
Flooring and foundation
Flooring
5. The SlimFit boiler is approved for installation on combustible
flooring, but must never be installed on carpeting.

2. Provide a solid foundation pad, at least 2 inches above the floor, if
any of the following is true:

Garage installation
Precautions
1. Take the following special precautions when installing the boiler
in a garage. If the boiler is located in a garage:
Mount the boiler at a height above the floor as specified in
the National Fuel Gas Code - ANSI Z223.1/NFPA54 –
latest edition for U. S. installations, or Natural Gas and Pro-
pane Installation Code - CAN/CSA B149.1 for Canadian
installations.
Locate or protect the boiler so it cannot be damaged by a
moving vehicle.
Ensure that the installation complies with all applicable codes.
Relocate Control Display, if desired:
Do not move the control display panel with the control
display communication cable connected. This could
damage or completely disable the boiler.
1. Remove lower portion of door panel beneath the control display
by pulling outward 3 inches on panel door handles. The panel
should rotate on bottom tabs. Then pull upward on panel door
handles to remove the panel from the boiler.
2. Reach behind the upper portion of the control display panel and
disconnect the RJ45 cable by pressing down on the phone jack
style tab, then pull the cable out of the display control board.
3. Use Phillips screwdriver to remove the two (2) screws from the
bottom two corners of the upper portion of the control display
panel, paying special attention that the control display commu-
nication cable is not being pulled with the panel.
4. Remove either of the other two burner end panels that is the
intended new location for the control display by lifting upwards
on the panel door handles.
5. Insert the upper portion of the control display panel downward
on the top frame in the new intended location of the control
display. Use a Phillips screwdriver to re-connect the panel to the
side and/or corner posts.
6. Move the plastic clip that supports the control display communi-
cations cable to a 0.25" hole closest to the new intended location
of the control display.
7. Re-insert the phone-jack-style connector back into the control
display board.
8. Replace the lower portion of the door panel beneath the control
display by inserting the three (3) tabs into the lower frame and
then rotating it towards the boiler until the latches snap into place.
9. Replace the non-control display door panel by aligning the three
tabs with the lower frame and sliding the door panel downward
onto both the top and lower boiler frames.
