PART 9 – START-UP PROCEDURE
FOR YOUR OWN SAFETY READ BEFORE OPERATING
1. This heater does not have pilot. It is equipped with an ignition device which automatically lights the burner. Do not try to light the
burner by hand.
2. BEFORE OPERATING: smell all around the heater area for gas. Be sure to smell next to the floor because some gas is heavier than
air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
Do not try to light any heater.
Do not touch any electric switch; do not use any phone in your building.
Immediately call your gas supplier from a neighbor's phone. Follow the gas suppliers' instructions.
If you cannot reach your gas supplier, call the fire department.
Turn off gas shutoff valve (located outside of the heater) so that the handle is crosswise to the gas pipe. If the handle will not
turn by hand, don't try to force or repair it, call a qualified service technician. Force or attempted repair may result in a fire or
explosion.
4. Do not use this heater if any part has been under water. Immediately call a qualified service technician to inspect the heater and to
replace any part of the control system and any gas control that has been damaged.
5. The heater shall be installed so the gas ignition system components are protected from water (dripping, spraying, rain, etc.) during
heater operation and service (circulator replacement, condensate trap, control replacement, etc.)
Failure to follow these instructions could result in property damage, serious personal injury, or death.
If you discover any evidence of a gas leak, shut down the heater at once. Find the leak source with a bubble test and repair
immediately. Do not start the heater again until the leak is repaired. Failure to comply could result in substantial property damage,
severe personal injury, or death.
A. CONTROL OVERVIEW
The control is one of the primary safety devices of the heater. It monitors the safety sensors of the heater to assure safe and efficient
operation.
The control has many features associated with system design. This section addresses programming features, including Heater Settings
/ System Settings / Maintenance Settings and System Diagnostics, to help in customizing your control. It is important to fully understand
control capabilities before customization, as its factory defaults may already fit your system design and not require any adjustment at
all.
B. NAVIGATION OF THE DISPLAY
The display includes a two line backlit LCD readout to provide informative messages about the operation of the heater. Many operating
parameters can be viewed and adjusted by using the six buttons on the display. The function of each button is described below.
RESET

arrow keys to
select the next digit to change and again use the
▼▲
keys to change the value. Repeat until the correct code is entered. Press the
ENTER
key to accept the code entered. If the code is correct, the readout will change to the appropriate screen. If the programming
code is not accepted, the readout will continue to display as shown above.
