• Excessive manifold gas pressure - see Table 4 on page 56

and manifold Gas Pressure Adjustment on page 56.

• Vent (exhaust) gas recirculation at the vent and intake air

pipe terminations on Direct Vent installations - see Direct

Vent installation on page 56.

• Excessive equivalent lengths of intake air and/or vent

(exhaust) piping installed - see Venting requirements on

page 56.

• Debris clogging/blocking the intake air screen(s) - see

Figure 17 on page 56 and Figure 22 on page 56.

• Debris clogging/blocking the main Burner - see Figure 2 on

page 56.

momentary ignition

Burn Hazard

Do not reach into the burner housing or

combustion chamber if the water heater

is still hot.

•

Allow the water heater to cool and always use

gloves when handling the main burner.

•

The combustion chamber and burner sleeve

and housing become very hot during operation.

CAUTION

if the main Burner ignites momentarily but does not sustain

ignition allow the water heater to try to ignite up to two more

times until control system locks out and the ignition Failure Fault

message is displayed on the control system's LCD. if the water

heater is experiencing rough starts - see rough Starting, rough

Operation on this page. For momentary ignition problems without

rough starting check the following:

• incorrect manifold gas pressure - see Table 4 on page 56

and manifold Gas Pressure Adjustment on page 56.

• Undersized supply gas line (low volume of supply gas) - see

Supply Gas Line on page 56.

• Supply gas regulator is not installed per installation

requirements (erratic gas supply volume/pressures) - see

Supply Gas regulator on page 56.

• See the list of possible causes and things to check and

repair for the ignition Failure Fault message on page 56.

• Debris clogging/blocking the intake air screen(s) - see

Figure 17 on page 56 and Figure 22 on page 56.

• Debris clogging/blocking the main Burner - see Figure 2 on

page 56.

not enough or no hot water

• No power to the water heater, check breaker, fuses and the

water heater on/off switch.

• Hot water supply valve(s) to fixtures closed.
• Operating Set Point is set too low, Differential setting is set

too high. See Control System Operation on page 56.

• Upper and/or Lower Probe Offset settings are causing the

heating cycles to terminate prematurely - see Temperatures

menu (cont) on page 56.

• Ensure there is not any external supervisory control (using

the enable/disable circuit) disabling heating operation. See

Enable/Disable Circuit on page 56.

• The heating capacity of the water heater has been

exceeded, the water heater is unable to meet demand.

operational problems

Read and understand this instruction

manual and the safety messages

herein before installing, operating or

servicing this water heater.
Failure to follow these instructions and

safety messages could result in death

or serious injury.
This manual must remain with the

water heater.

This section of the manual is intended to be an aid in correcting

common operational problems, it is not all inclusive. The installer

may be able to observe and correct certain problems which

might arise when the water heater is first put into operation or

when it is re-fired after a prolonged shutdown. However, only

qualified service agents, as defined in Qualifications on page 56,

using appropriate test equipment, should perform any service

procedures on the water heater.

note:

Call the technical support phone number listed on the

back cover of this manual for further technical assistance or to

locate a qualified service agent in your area.

installation errors

Operational problems on new installations are often the result of

installation requirements that have been overlooked rather than

failed components. iE: A "Low Gas Pressure" Fault condition

is most often caused by low supply gas pressure rather than a

defective Low Gas Pressure switch. rough starting and rough

operation are often caused by undersized supply gas lines and/

or the absence of a supply gas regulator at the water heater.
Prior to performing any operational checks inspect the water

heater installation to ensure all installation requirements and

instructions have been maintained and followed. See the

installation Checklist on page 56

note:

Costs to correct installation errors are not covered under

the limited warranty.

rough starting, rough operation

Fire and Explosion Hazard

Turn off gas lines during installation.
Contact a qualified installer or service

agency for installation and service.

Excessive gas pressure to gas valve can

cause serious injury or death.

Do not use water heater with any gas

other than the gas shown on the rating

label.

• Undersized supply gas line (low volume of supply gas) - see

Supply Gas Line on page 56.

• Supply gas regulator is not installed per installation

requirements (erratic gas supply volume/pressures) - see

Supply Gas regulator on page 56.

• Excessive supply gas pressure - see Table 4 on page 56

and Supply Gas Pressure Adjustment on page 56.
