Leak Testing

The water heater and its gas connections 

must be leak tested at normal operating 

pressures before it is placed in operation.

   Turn on the manual gas shut-off 

valve near the water heater.

   Use a soapy water solution to test for 

leaks at all connections and fittings. 

Bubbles indicate a gas leak that must 

be corrected. 

The factory connections to the combina-

tion gas control should also be leak tested 

after the water heater is placed in opera-

tion.

High Altitude

Pressure Testing the Gas Supply System

The water heater and its individual shut-

off valve must be disconnected from the 

gas supply piping system during any 

pressure testing of that system at test 

pressures in excess 1/2 psi (3.5 kPA).

The water heater must be isolated from 

the gas supply piping system by closing 

its individual manual gas shutoff valve 

during any pressure testing of the gas 

supply at test pressures equal to or less 

than 1/2 psi (3.5 kPa).

WARNING: Never use 

an open flame to test for 

gas leaks, as property 

damage, personal injury, or 

death  could result.

Vent and Combustion Air-Inlet

This water heater is a direct vent appli-

ance and must be installed so that all air 

for combustion is derived directly from 

the outside atmosphere and all flue gases 

are discharged to the outside atmosphere.  

For proper installation of the vent and 

combustion air-inlet systems, follow the 

instructions as detailed in this manual. 

DO NOT

 connect this water heater to 

an existing vent or chimney - it must be 

vented separately from all other appli-

ances.
NOTICE: This water heater is approved 

to use the following materials for pipe of 

the vent and Combustion Air-Inlet sys-

tems:
PVC (Schedule 40, Cellular Core, 

ASTM-F891)
PVC (DWV, ASTM-D2665 or CSA 

B181.2)
PVC (Schedule 40, ASTM-D1785 or CSA  

B137.3)
PVC (SDR Series, ASTM-D2241 or CSA 

B137.3)

CPVC (CPVC 4120, ASTM-D2846 or 

CSA B137.6)
CPVC (Schedule 40, ASTM-F441 or CSA 

B137.3)
CPVC (SDR Series, ASTM-F442)
ABS (Schedule 40, DWV, ASTM-D2661 

or CSA B181.1)
ABS (Schedule 40, DWV, Cellular Core, 

ASTM-F628)
This water heater is approved to use the 

following materials for the fittings of the 

vent and combustion air-intake systems:
PVC (Schedule 40 DWV, ASTM D2665)
CPVC (Schedule 40, ASTM F438)
ABS (Schedule 40 DWV, ASTM D2661)

DO NOT mix ABS pipe and fittings 

with PVC or CPVC pipe fittings. Note: 

It is acceptable to interchange PVC and 

CPVC pipe and fittings.

Vent and combustion air-inlet systems 

must be adequately supported along both 

vertical and horizontal lengths.

DANGER: Failure to 

properly install the vent and 

combustion air-inlet systems as 

outlined in the Vent and 

Combustion Air-Inlet section of 

this manual will result in 

unsafe operation of the water 

heater causing bodily injury, 

explosion, fire or death. 
To avoid the risk of fire, 

explosion, or asphyxiation from 

carbon monoxide, NEVER 

operate the water heater unless 

it is properly vented and the 

vent and combustion air-inlet 

systems are properly installed 

as detailed in the "Vent and 

Combustion Air-Inlet" section 

of this manual.
The vent and combustion air 

inlet pipes must overlap a 

minimum of 1/2 in. (1.3 cm) 

at each joint.  It is important 

that the vent and combustion 

air-inlet pipes engage fully into 

any pipe fitting and be kept in 

that position until the adhesive 

has fully cured.  DO NOT drill 

or punch holes in the plastic 

pipe or fittings.

Input rating of this water heater is based 

on sea level operation.  At higher eleva-

tions the actual input rate may be lower 

than the value listed on the rating label 

due to the derating of Natural Gas and LP 

Gas.  For Power Direct Vent models listed 

in the venting tables that do not show 

venting configurations above 7,700 ft. 

(2,347 m), contact the water heater manu-

facturer for a required High Altitude Kit 

that will allow the specific water heater 

model to operate at altitudes between 

7,700 ft. (2,347 m) and 10,200 ft. (3,109 

m),(see page 40).

!

WARNING: Failure to 

install a water heater suitable 

for the altitude at the location 

it is intended to serve, can 

result in improper operation 

of the appliance resulting 

in property damage and/or 

producing carbon monoxide 

gas, which could result in 

personal injury, or death.
