Siting and Maintenance
Grant Approved Installers
Grant pellet boilers must only be fitted and commissioned by a heating installer who has been fully trained and approved by Grant under the G-One Scheme. Failure to comply with this may result in the product warranty becoming invalid.
Siting the appliance and store
Wood pellet boilers are generally larger than traditional oil or gas boilers and also require a large hopper to store fuel. The Grant Spira is designed to be sited in a garage or store. Therefore before purchasing, it is important to consider where it will be located.
Ventillation should be provided to the boiler room to provide adequate air supply allowing the appliance and flue to operate efficiently. An air vent either directly to an external air source or vented into a room that has an external vent direct to an air source must be used.
It is also important to bear in mind that the boiler will carry out a sporadic cleaning cycle. This process will result in a temporary increase in noise level, so should also be considered when choosing a suitable location.
Pellet Storage
It is very important to ensure you have sufficient space to store the wood pellet fuel. A bulk hopper system can be employed for greater pellet storage e.g. four tonne hopper. This can be fed directly into the intermediate Grant pellet store supplied as standard with the boiler. When using larger storage, it is also important to consider vehicle access, as bulk delivery lorries need to blow pellets into the hopper.
Stores are available in internal and external versions and only an approved storage system can be used with the Grant Spira, as the pellets must be kept free of moisture. Failure to follow this instruction can result in poor boiler operation and may invalidate the warranty
Boiler set up
The boiler burner comes pre-set for ‘Grant Approved’ premium wood pellets, which ensures efficient burning with maximum temperature output. To use another approved premium wood pellet, the burner settings may need to be re-set to the particular attributes of that fuel. This will ensure the appliance operates efficiently. Contact Grant for further information.
Looking after your pellet boiler
One of the best features of the Grant Spira is that it requires very little maintenance, compared with other wood pellet appliances. The unit itself has an automatic wash-clean system for the condensing system to ensure it stays free of debris. It also features a self cleaning burner and combustion chamber. As a result of the boiler’s efficient operation, the ash pan only needs emptying after every three tonnes of pellets consumed and servicing just once a year (under normal operation).
Service and maintenance
As part of the installation package, your Grant Spira Wood Pellet boiler will be routinely maintained and serviced for the first two years by your G-One installer.In the unlikely event of a problem occurring, you must first contact your G-One installer to attend the fault. If it cannot be rectified, they should telephone the Grant Customer Service Department on: 01380 736920.
