Install the appliance in an area that allows for service and maintenance access
to utility connections, piping, ductwork, lters, and traps. Based on the installa-
tion location, ensure the following clearances are maintained:
Minimum clearance: Clearance to
combustibles
Recommended

Part # 85477
The GF200 is congured for
Natural Gas from the factory.
If conversion to Propane Gas
is required, the conversion kit
supplied with the water heater
must be used.
• Before connecting the gas supply, determine the gas type and pressure
for the water heater by referring to the rating plate. Use only the same
gas type indicated on the rating plate. Using a dierent gas type will
result in abnormal combustion and malfunction of the water heater.
Gas supplies should be connected by a licensed professional only.
• The appliance and its gas connection must be leak tested before
placing the appliance in operation.
• The water heater cannot be converted from natural gas to propane or
vice versa without the supplied gas conversion kit. Do not attempt a
eld conversion of the water heater without a the gas conversion kit.
Doing so will result in dangerous operating conditions and will void the
warranty.
NTI is not liable for any property damage and/or personal injury resulting
from improper conversions.

4Return Air Ducting
The return air may be delivered to the
appliance via:
a) either side;
b) the back;
c) the bottom; or
d) any combination thereof, provided, in
all cases, that access to at least one side
door remains clear (24” min.) for blower
access and maintenance.

In all installations, an appropriate air ltration system is recommended and
must meet test requirements in UL 900. Failure to install and properly main-
tain such a system could lead to damage to and/or premature failure of the
space heating components.
In all cases, care must be taken to ensure that return ducting is sealed against
the inlet, such that the entire air steam is directed through the air lter. Failure
to do so could cause damage to the air moving equipment and clogging of
the heating and/or cooling coils.
NOTE: For details and recommendations on side, back or bottom return ducting see

Exhaust Vent Materials
From factory, the GF200 operates at water temperatures exceeding 150°F,
resulting in the potential for exhaust temperatures to exceed 149°F.
As such, high-temperature vent pipe material (CPVC or polypropylene; see table
below) must be used for the rst 3 feet (2" venting) or 0.5 feet (3" venting).
If such materials are unavailable, see the Venting section of the GF200 manual for
instructions on how to limit the maximum water temperature set point.
* Approved polypropylene systems include: Duravent Polypro (Single Wall): 2PPS-
xxx (2in), 3PPS-xxx (3 in) / Centrotherm Innoue SW: ISxx02xx (2 in), ISxx03xx (3 in)
/ Centrotherm InnoFlue Flex: IFVL02XXX (2 in). Refer to the manufacturer’s litera-
ture for detailed information.
** For installation in Canada, eld-supplied plastic vent piping must comply
with CAN/CGA B149.1 (latest edition) and be certied to the Standard. For Type
BH Gas Venting Systems, ULC-S636. Components of this listed system must not
be interchanged with other vent systems or unlisted pipes or ttings. All plastic
components and specied primers and glues of the certied vent system must
be from a single system manufacturer and must not be intermixed with another
system manufacturer’s parts. The supplied vent connector and vent termination
are certied as part of the water heater.

the cabinet. Failure to do so could cause severe injury or death.

Determine which side of the appliance the gas, inlet water, and outlet
water connections will be made on.
A) Left side connections
B) Right side connections
C) Both - One (or more) on each side
NOTE: Typically, both water connections are installed on the opposite
side of the return air duct to allow for air lter & maintenance clearances.
ATTACH O-RING
PN: 85369
NOTE: wet the
outer surface of
the O-ring for
easier insertion.
Install the plug adapters in the unused inlet and outlet connections.

Install the O-rings and re-insert the t-

Take care not to damage the O-rings with
excessive heat.

A tempering valve must be
installed on the hot water
outlet to prevent scalding.
Pressure
Relief Valve
Improper installation of the
pressure relief valve may
result in property damage,
personal injury, or death.
Follow all instructions and
guidelines when installing
the pressure relief valve.
The valve should be in-
stalled only by a licensed
professional.
To complete the installation of the appliance, you must install an approved 3/4 in,
maximum 150 PSI pressure relief valve (PRV) on the hot water outlet.
The water heater has a built-in high temperature shut o switch, so install a
“pressure only” relief valve. This valve is not supplied, but is required.
The PRV should be placed as close to the hot water outlet as possible. No other
valve should be placed between the PRV and the appliance.

Connection Side
This appliance is shipped from factory with a condensate drain pre-installed
on the right side. To switch sides, refer to the GF200 Installation Manual.
To connect the condensate drain:
1. Connect a drain line to the 5/8 in barbed tting at the side of the appliance. Secure
with hose clamp. Use only corrosion-resistant material for the drain line, such as PVC
or CPVC. Do not reduce the size of this tting or the drain line to less than 1/2 in.
2. Place the free end of the drain line into an appropriate drain.
3. If you are using a condensate pump, ensure that the pump allows for up to 2 GPH
of drainage. If you are not using a condensate pump, ensure that the drain line is
pitched downward at a minimum slope of 1/4 in per foot.
Before connecting the con-
densate drain, choose one
of the following disposal
options:
a. Direct to drain
b. Drain via neutralizer
c. Direct to laundry tub
d. Laundry tub via con-
densate pump

Recommended Gas Pressure Settings:
NG: 3.5” – 10.5” w.c.
LP*: 8.0” – 13.0” w.c.
To connect the gas supply:
1. Determine the gas type and pressure for the appliance by referring to the rating plate.
2. Perform a pressure test on the main gas supply line. For detailed instructions to meas-
ure the inlet gas pressure, see relevant section in the water heater installation manual
(supplied).
3. Determine the proper size and type for the gas line. Purge the gas line of any debris.
4. Install full port valves on the gas supply line and appliance.
5. Connect the gas supply line. Test it, all connection points, and the GF200 for gas leaks.
6. Shut o manual gas valve and run a hot water faucet (until the water heater shuts o
due to lack of fuel) to purge the gas line.
7. Re-open the manual gas valve and open several high ow rate xtures to ramp the
water heater up to its maximum ring rate.
8. Check the inlet gas pressure reading on the manometer as shown below.
9. If readings are out of range: adjust the inlet gas pressure regulator.
Recommendation:
Install GF200 as
rst appliance
downstream of
meter
Gas Supply Line
Gas meter’s capacity ≥ Total gas
capacity of connected appliances
It is recommended that this appli-
ance be connected as the rst one
downstream of the gas meter to
ensure a sucient gas supply.
●Tighten the appliance connection
valves with care to avoid damage.
●It is recommended that a union be
installed on the gas supply line close
to the appliance, to facilitate any
future maintenance or service.
●Gas connection is possible from both
sides. A union inside the cabinet will
help improve access to plumbing
and lters when routing gas line
from right side.
