No orifice change is required for high-altitude
installations. The Control automatically ad-
justs boiler operation for altitude when set
properly. Select “
9%3 ” in the Control setup
for the (IGH!LTITUDE option (see Figure 62,
page 73).
6ERIFYORIlCESIZE
See Figure 2, page 10. Verify when installing the
propane orifice that the orifice size marking
matches boiler size.
Model 750 boilers also require installation of
a blower orifice for propane operation. The
orifice is supplied in the propane conversion
kit.

Boiler Manual
Prepare boiler
Install propane orifice — SF-550 or -750
)FBOILERISALREADYINSTALLED — You must turn
off electrical supply to the boiler and close the
external manual gas shut-off valve to isolate the
boiler during conversion. Allow the boiler to cool
if it has been operating. Following conversion of
an installed boiler, follow all instructions in this
manual to start up the boiler and verify operation
of the boiler and all system components.
SF-550 boilers are shipped with a blower plate that is
used for natural gas and propane. The blower plate
must be left in place for propane applications.
Vent and air piping requirements (page 20)
1. The SlimFit boiler requires a special vent system, designed
for pressurized venting.
a. SlimFit boilers are rated ANSI Z21.13 Category IV (pres-
surized vent, likely to condense in the vent).
b. SlimFit commercial boilers can be either DIRECTEXHAUST
(vent to the outside, combustion air from inside) or
DIRECTVENT (vent and air piped outside).
c. See instructions beginning on page 20 for vent/air con-
figuration options and installation requirements.
2. Note “Prevention of combustion air contamination” on
page 22 when considering vent/air terminations and boiler
room conditions when using inside air (direct exhaust in-
stallation).
3. Be sure to locate the boiler such that the vent and air piping
can be routed through the building and properly terminated.
The vent/air piping lengths, routing and termination method
must all comply with the methods and limits in instructions
beginning on page 21.
Remove boiler from crate
Cold weather handling — If boiler has been stored in a
very cold location (below 0°F) before installation, handle
with care until the plastic components come to room
temperature.
Do not lift or handle the boiler by the water or gas
pipes.
1. Leave boiler on crate base until ready to place in final location.
2. Cut the retaining straps. Make sure the boiler is sitting se-
curely.
3. Remove outer shipping carton from boiler.
Leave the plastic cover on the boiler vent outlet until
ready to attach vent piping. This will prevent debris from
falling into the vent adapter.
4. After removing the packaging, lift boiler from the skid and
place in position.
Do not drop the boiler. Damage to boiler com-
ponents can result.

. The base must be in good
condition and sealed tightly for proper operation
of the boiler.
Placing the boiler
1. Set the boiler in place and check level. Use shims if necessary
to level the boiler (and condensate pump, if used).
