6. Inside the firebox, remove the air metering plate (just in front of the burner – three
screws) and lift out the draught deflector. Remove the four burner retaining screws.

ROUTINE MAINTENANCE SCHEDULE
We recommend that you have your Masport heater checked yearly by an
Authorised Technician.
This periodic maintenance should cover the following points:-
1. Replace the filter in the control valve (Boston models only).
2. Replace the battery in the igniter module (Calgary only). Access the battery by
unscrewing the black top cap surrounding the red ignition press button. One AA
alkaline cell required.
2. Clean all air entry points such as primary and secondary air inlet passages.
3. Clean the main injector jet hole(s).
4. Clean the fan of any lint or foreign matter.
5. After the above steps, check the operation of the pilot, the main burner and the
control valve by lighting the fire.
6. Check the operation of the thermostat (Calgary models) by turning its control point
above and below the ambient room temperature and checking the response of the
fire.
Other points which can be checked after completing the above are:-
1. Thermocouple generation.
2. Gas consumption rate.
3. Carbon dioxide content in the combustion products.
4. The flue operation. (Boston models only).
Note: To ensure satisfactory performance, all components fitted should
be genuine Masport spare parts.
