

Verify Start-up Preparation items outlined

on pages 51 thru 53 have been completed.



Verify all electrical connections are

correct and securely fasten.



Inspect vent piping and combustion air

inlet piping for signs of deterioration from

corrosion, physical damage or sagging.

Verify combustion air piping and vent pip-

ing are intact and correctly installed.



Verify Burner Configuration - Propane

Only.

Check for proper labeling on the gas

valve, combustion air inlet and the rat-

ing label for propane configuration.

If there is doubt on the burner configu-

ration, remove the gas valve and check

for proper propane orifice. Refer to

outlined on page 52.

If PERFORMANCE PLUS Does Not Start

C o r re c t l y

1. Check for loose electrical connections,

blown fuse or open service switch.

2. Check continuity across the Low Water

Cut-Off device for close circuit.

3. Is the manual limit control open? Ensure the

manual limit is reset to the close position.

4. Is the gas supply valve open at the unit and

meter?

5. Is incoming gas supply pressure more than

5”w.c. for natural or propane with all gas

appliances operating

6. Are the heating thermostats set below room

temperature?

If none of these conditions correct the problem,

refer to the PERFORMANCE PLUS Trouble-

shooting guide.

Check the PERFORMANCE PLUS and

System



Check Domestic Piping.

Check domestic piping and system

components for leaks. If found, shut

down the unit and repair immediately.



Check Primary Piping.

Check primary system piping and com-

ponents for leaks. If found, shut down

the unit and repair immediately.

P u r ge any remaining air from the system

piping. Air in the system piping will

interfere with circulation creating heat

distribution problems and system noise.



Check Vent Piping and Combustion Air

Piping.

Check for gas-tight seal at every con-

nection and seam of the venting and

combustion air inlet.
