1. Quick Guide to Trouble shooting

This section outlines the most common problems and helps to guide you through the rest

of the workshop manual. (Read this section rst, before you make any adjustments. It

will save you time.)

CHECK HOT WATER SYSTEM FIRST, BEFORE THE CENTRAL HEATING CIRCUIT

HOT WATER SYSTEM

Here are some common problems:

GAS REGULATORS

Single appliance low capacity gas regulators plus 3/8” exible low pressure pipe, will

reduce the eciency dramatically. Ensure gas regulators and pipes are capable of

delivering 37mbar at the inlet under full load. A 2.5mbar drop is acceptable.

WATER FILTER

Check for contamination with foreign objects such as sawdust, plastic pipe swarf, etc. The

water lter is located inside the cold water inlet tting under the boiler. Any blockage will

reduce ow and may prevent the boiler ring up.

HOT AND COLD WATER CONNECTIONS

Connections may be reversed at the boiler inlet/outlet fittings, resulting in the boiler failing

to commence ignition sequence. This is because the hydraulic valve operates in one

direction only.

THERMOSTATIC SHOWER MIXER VALVE

Faulty non return valves within the mixer tap may allow mains cold water to enter the

domestic hot water pipe work. The boiler will react to the situation according to the

amount of mains water entering the system. In severe cases a high percentage of mains

cold water will exit the hot water tap in place of hot water, as water will always take the

path of least resistance. This will result in no hot water ow, or a very restricted flow

through the boiler. This will result in no ignition occurring or the boiler will modulate at very

low gas pressure, followed by the boiler eventually shutting down as insucient ow

passes through the boiler.
