Indicates a potentially hazardous situation which, if ignored, can result in death, serious injury or sub-

stantial property damage.

Indicates a potentially hazardous situation which, if ignored, can result in minor injury, property damage.

Indicates special instructions on installation, operation or maintenance, which are important to the equip-

ment/product, but not related to personal injury hazards.

This guide is to be used in conjunction with the PRESTIGE Boiler Installation and Maintenance Manual.

Procedures and servicing listed in this manual must be performed by a qualified service technician,

installer, service agency or gas supplier. Any procedures or service performed by an unqualified individ-

ual or service agency can result in severe personal injury, death or substantial property damage.

Introduction

This guide is to be used in conjunction with the Triangle Tube PRESTIGE Boiler Installation and Maintenance Manual.

Good Troubleshooting Practices

Before leaving for the job site:

Check your parts and tools

• Test equipment and tools you will need:

Electrical meter that tests both voltage (AC/DC), continuity (ØW), resistance ( W,ohms), and frequency (Hz)

Temperature gauge or metering device

Manometer

Calibrated Combustion Analyzer

Standard tools of the trade (wrenches, screwdrivers...)

• Parts to solve most problems

Control module

Transformer with surge protection

Blower with gasket

PS 399 Parts Case - PSR IT102

PS 60-250 Parts Case - PSR IT103

Review all appropriate manuals before leaving for the job site

At the job site:

- Clarify problem

- Have the PRESTIGE manual and any other wiring, zone control or piping diagrams, or installation guides readily

available.

REMEMBER

Follow the Troubleshooting Guide step by step, always double checking your results. Skipping steps or not complet-

ing steps can lead to wrong conclusions, repeated visits to the job site, unhappy customers and unnecessary warran-

ty claims.

Servicing Tips and Instructions

Label all wires and wire connections prior to disconnecting when servicing any boiler controls. Wiring errors

can cause improper and dangerous operation. Always disconnect the power supply to the boiler before serv-

icing. Failure to comply could result in severe personal injury, death or substantial property damage.

Never bypass (jumper) any boiler, control or device except for momentary testing when troubleshooting the

boiler as outlined in this guide, severe personal injury, death or substantial property damage can result.

Initial Troubleshooting Checks

- Ensure all wire connectors to the control module and sensors are securely connected.

- Ensure the maximum gas supply pressure does not exceed 13”w.c. during flow or no flow conditions.

- Ensure the gas supply pressure is a minimum 5” w.c. during flow conditions (burner firing on all gas appliances).

Control Module Fuses

The control module contains 2 internal replaceable fuses. Ensure the fuses are in working condition prior to

replacing the control module or any boiler component. If one of the fuses has blown, it will prevent the con-

trol module and/or boiler components from operating properly.

To check or replace the control module fuses:

1. Disconnect the external power supply to the boiler.

2. Remove the front jacket panel of the boiler by removing the thumb screw along the top edge.

3. Remove the electrical connectors at the MCBA control module for the igniter, transformer and display (ribbon

cable) and the black plastic housing cover off the control module. Use care not to damage the cover when

removing it.

4. Remove both fuses and check for continuity to determine if fuse is blown, replace if necessary.

5. The control module is supplied from the factory with 2 spare fuses, a 5 amp fast acting fuse and a 4 amp slow

acting fuse, attached to the control module cover.

6. When replacing the fuses ensure the amp rating and type of the fuse matches the replacement fuse. Reference

Fig. 1, page 4 for amperage and location of the fuses.

Do not bypass any fuse with a jumper. Do not replace any fuse with a fuse that is not specified. Failure to

comply could result in severe personal injury, death or substantial property damage.

7. Re-install the control module cover, electrical connectors and the front jacket panel when completed.

WARNING

NO ICE

8. Reconnect the external power supply to the boiler and perform the verification of operation steps as outline in

the Prestige Installation Manual.

After completing any servicing of the boiler verify proper operation of the boiler. Steps to verify proper oper-

ation are outlined in the Start-Up Procedures in the PRESTIGE Boiler Installation and Maintenance Manual.

Failure to comply could result in severe personal injury, death or substantial property damage.

Standby Mode

After the boiler is turned on, the control panel will be in the

STANDBY mode.

This is the standard mode for the PRESTIGE. The control

automatically returns to this mode after 20 minutes if no

keys have been pressed on the display. Any parameters

that were modified are then stored.

The first character shows (on the left side of the display)

the current status of the boiler depending on the condition

of both the boiler and the burner. The last 3 characters

indicate the boiler supply temperature.

If the burner is blocked due to a “soft” lockout, the display

alternates between a 9 followed by the boiler supply tem-

perature and “b” with a two digit error code. See page 12

-17 for detailed information on the corrective and preven-

tive actions for the soft lockouts.

T TEMP RARILY PLACE THE BURNER

hold both the MODE and “+” buttons simultaneous-

ly until the first digit flashes “H”.

While in the test mode:

- high limit will function

- boiler CH circulator will function

- domestic circulator will not function

- the test mode will time out in approximately

10 minutes

TEST M DE: press the MODE button until

“StbY” is displayed. hen press and hold both the

“+” and “-” buttons simultaneously to deactivate the

high or low fire test mode.

If the “+” button is held in, the CH system

(parameter 3) will be turned FF and the dis-

play will show “cOFF”. Press and hold the “+”

button to turn the CH system back N, the dis-

play will show “c” followed by CH set point. If

the “-” button is held in while in the “StbY”

mode, domestic system (parameter 2) will be

turned FF and the display will show “dOFF”.

Press and hold “-” button to turn the domestic

system back N, the display will show “d” fol-

lowed by domestic set point temperature.

Parameter Mode

To access PARAMETER mode when the system is in

STANDBY mode, press the MODE button once.

To scroll through the list of parameters, simply press the

“STEP” button. The First digit is the parameter number fol-

lowed by the parameter value. To modify a parameter

value, use the + or - keys. Then press “STORE” to save

the value you just changed. The display flashes once to

confirm the data has been saved.

To activate the parameters you changed, press RESET.

However, if you do not press a key, the system returns to

STANDBY mode after 20 minutes and automatically

stores the changes.

Note 1: This parameter is factory set to 140ºF. It is impor-

tant to note the control adds 46ºF to this setting, therefore

the actual domestic hot water boiler setpoint is 140ºF +

46ºF = 186ºF.

Note 2: This parameter should not be changed from the

factory setting of 01. The performance of the DHW

(Domestic Hot Water Heating) will be affected and can

become unreliable.

Note 3: This parameter should not be changed from the

factory setting of 01. The performance of the CH

(Central/Space Heating) will be affected and can become

unreliable.

For example:

Write the numbers down from left to right to

arrive at 123,456 CH ignitions.

In the INF Mode a temperature reading of

-22 typically indicates an “open” circuit. A

temperature reading of 240 typically indicates

a short-circuit.
