REQUIREMENTS FOR THE
COMMONWEALTH OF
MASSACHUSETTS
The following requirements reference various
Massachusetts and national codes not contained
in this manual. For all sidewall horizontally vented
gas fueled equipment installed in every dwelling,
building or structure used in whole or in part for
residential purposes, including those owned or
operated by the Commonwealth and where the
side wall exhaust vent termination is less than (7)
feet above nished grade in the area of the venting,
including but not limited to decks and porches, the
following requirements shall be satised:
INSTALLATION OF CARBON MONOXIDE
DETECTORS
At time of installation of side wall horizontally vented
gas fueled equipment, the installing plumber or
gas-tter shall observe that a hard wired carbon
monoxide detector with an alarm and battery
back-up is installed on the oor level where the
gas equipment is to be installed. In addition, the
installing plumber or gas-tter shall observe that
a battery operated or hard wired carbon monoxide
detector is installed on each additional level of the
dwelling, building or structure served by the side
wall horizontal vented gas fueled equipment. It shall
be the responsibility of the property owner to secure
the services of qualied licensed professionals for
the installation of hard wired carbon monoxide
detectors. In the event that the side wall horizontally
vented gas fueled equipment is installed in a crawl
space or attic, the hard wired carbon monoxide
detector with alarm and battery back-up may be
installed on the next adjacent oor level. In the
event that the requirements of this subdivision can
not be met at the time of completion of installation,
the owner shall have a period of thirty (30) days to
comply with the above requirements; provided,
however, that during said thirty (30) day period, a
battery operated carbon monoxide detector with
an alarm shall be installed.
APPROVED CARBON MONOXIDE
DETECTORS
Each carbon monoxide detector as required in
accordance with the above provisions shall comply
with NFPA 720 and be ANSI/UL 2034 listed and IAS
certied.
SIGNAGE
A metal or plastic identication plate shall be
permanently mounted to the exterior of the
building at a minimum of eight (8) feet above
grade directly in line with the exhaust vent terminal
for the horizontally vented gas fueled heating the
appliance or equipment. The sign shall read, in
print no less the one-half inch (1/2”) in size, “GAS
VENT DIRECTLY BELOW. KEEP CLEAR OF ALL
OBSTRUCTIONS”.
INSPECTION
The state or local gas inspector of the side wall
horizontally vented gas fueled equipment shall not
approve the installation unless, upon inspection, the
inspector observes carbon monoxide detectors and
signage installed in accordance with the provisions
of 248 CMR 5.08 (2) (a) 1 through 4.
EXEMPTIONS
The following equipment is exempt from 248 CMR
5.08 (2) (a) 1 through 4: The equipment listed in

according to thickness of the wall, (see table 3):
• (B) vent pipe
• (C) vent-air intake pipe
• (i) insulation
• (D) rod
2. The hole at the outside of the wall must be a
square of 11-1/4” (286 mm) x 11-1/4” (286 mm) (see
gure 28).
3. Slide the heat shield (K) into the 11-1/4” (286
mm) x 11-1/4” (286 mm) square hole. Secure the
heat shield (K) to the wall bracket using the
appropriate hardware.
4. From the outside of the wall, screw the rod
(D) slightly onto support located inside the
appliance ue outlet.
5. Wrap the vent-air intake pipe (C) with the
provided insulation (i) (foil side out) and place
the provided strip of tape (H) down the seam to
secure it.
6. Slide the smaller vent pipe (B) (from outside
your house) through the hole in the wall and
attach to the mounted heater inside your house.
Be sure the vent pipe is snug and engaged to
the heater. Then slide the larger Vent‐Air Intake
Pipe, with the insulation wrapped and taped to
the outside of the pipe, through the same hole
and over the smaller Vent Pipe (B) and attach to
the heater.
NOTE: It is critical that the insulation wrap (i) be
wrapped and secured with the tape on the outside
of the larger Vent‐Air Intake Pipe (C). The insulation
is NOT to be wrapped in between Vent Pipe (B) and
Vent‐Air Intake Pipe (C) (see gure 27).

the vent cap (A) and the exterior wall. Note: For
additional security the outdoor mounting plate
(F) can be attached to the outside of the wall
using the appropriate hardware for mounting
to the surface of the building. The outdoor
mounting plate (F) must be positioned ush
to the wall and sealed with a non-hardening
mastic (silicone caulk). Position the outdoor
mounting plate (F) so that the vent-air intake
pipe (C) has a slight upward slope of 1/4” per foot
of venting to the outside.
8. Before attaching the vent cap (A) to the exterior
wall, run a bead of non-hardening mastic
(silicone caulk) around its outside edge, so
as to make a seal between it and the outdoor
mounting plate (F) (see gure 29).
9. Slide the vent cap (A) into position and secure
into place using the provided nut (E). Tighten
nut (E) down until the vent cap (A) leans against
the outdoor mounting plate (F).

INSTALLING THE THERMOSTAT SENSOR
In order to protect the thermostat sensor from
any damage during shipping, or while handling
it before it is denitely installed, the thermostat
sensor has not been attached to its nal location in
the appliance. So, once the heater is installed, the
thermostat sensor must be placed and secured in
position. To do so, follow these steps:
1. Reach in through the bottom of the unit and
cut the cable tie holding the thermostat sensor
to the unit.

QUALIFIED TECHNICIAN
SELECTOR VALVE
Note: If you are connecting this appliance to
propane do not make any adjustments. Proceed
to installing the gas line as instructed in the
Owner’s Manual.
1. If you are connecting to Natural Gas, remove
the access panel. Rotate the knob clockwise
until the arrow on the knob lines up with NG
label on the appliance.
2. Replace the access panel.
GAS CONNECTION
1. We recommend using only new black iron or
steel pipe. CHECK LOCAL CODES.
2. The gas supply line shall be sized and installed
to provide a sufcient supply of gas to meet
the maximum demand of the heater without
undue loss of pressure.
3. The sealant used on the threaded joints of the
gas pipe must be a type resistant to the action
of L.P. Gas. (This sealant should be applied
lightly to main threads to ensure excess sealant
does not enter lines.)

4. The gas supply system must include a manual
shut off valve and connection in the line, so the
heater can be disconnected for servicing. (See
Figure 32).
5. Include a drip leg (trap) and a plugged 1/8”
N.P.T. tapping in the line. The tapping should be
accessible for test gauge connections upstream
of the gas supply connection to the heater.
