2.0 GRANT RESEARCH AND
DEVELOPMENT COMBUSTION AT
ALTITUDE
The R&D department of Grant Engeeniring located in Birr (Grant
Headquarters) in Ireland, are aware of the challenges of fuel oil
quality at altitude, has created an altitude chamber in its laboratory
in order to test all the burners capable of operating on territory at
any altitude.
The results allow Grant to guarantee the use of its boilers under nor-
mal conditions of use at the altitudes mentioned in Table 2.3 below.
For an even better adaptation, we are preparing kits for operation
at higher altitudes.
* For altitude adaptation of Grant vortex boilerhouse combi 52kw
and 66kw boilers, please contact us at info@heatmax.gr
