Maintenance and inspection

Visually inspect the venting system for proper size and horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.
Maintenance and inspection of the boiler must be carried out at the following occasions:
• When a number of similar error codes and/or lock-outs appear.
• At least every 12 months maintenance must be done to ensure safe and efficient operation.
Damage caused by lack of maintenance will not be covered under warranty
