FUNCTIONAL INTRODUCTION
The VGH b oilers are cent ral heatin g/combi boilers w ith a maximu m high effici ency. Such a performance c an be
reached by, amongst o ther things, using a sp ecial heat exchanger m ade of stainless stee l. This allows the flue
gases to cool down below the condensation point, thus releasing extra heat. This has an immediate positive impact
on the efficiency.
The VGH boiler is factory set for Natural gas.
Fuel used must have Sulphur rates with a maximum a nnual peak over a s hort pe riod of tim e of 150 mg/m
3
ppm) and an annual average of 30 mg/m
. (22 ppm average).

How to calculate De-rating at intermediate elevations for US:
Elevation between:
2000 and 3000 ft : (New value – 2000) x 0.004 Example: Elevation is 2600 ft. De-rating is (2600-2000)x0.004 = 2.4 %
3000 till 4000 ft : ((New value – 3000) x 0.004)+4 Example: Elevation is 3700 ft. De-rating is ((3700-3000)x0.004)+4 = 6.8 %
4000 till 4500 ft : ((New value – 4000) x 0.004)+8 Example: Elevation is 4200 ft. De-rating is ((4200-4000)x0.004)+8 = 8.8 %
Above 4500 ft : ((New value – 4500) x 0.004)+10 Example: Elevation is 4800 ft. De-rating is ((4800-4500)x0.004)+10 = 11.2 %
How to calculate De-rating at intermediate elevations for Canada:
Elevation between:
2000 till 4500 ft : All values de-rate by 10% Example: Elevation is 3600 ft. De-rating = 10 %
Above 4500 ft : ((New value – 4500) x 0.004)+10 Example: Elevation is 7600 ft. De-rating is ((7600-4500)x0.004)+10 = 22.4 %

• Do not install the boiler in a location where it w ill be exposed t o high levels of humi dity and moisture or
where condensation might fall onto the boiler.
• Make sure there is an open connection to the s ewer to drain the c ondensate. This conn ection must be
lower than the condensate drains level of the boiler. If not, a condensate pump will be required.
• Do not locate the boiler in an area which contains corrosive or other contaminants as outlined in section
9.8.1, especially Table 9.11 and Table 9.12.
• When considering installation locations, consideration must be given to the combustion air supply,
specifically whether to use indoor air or sealed combustion.
• Do not allow the combustion air to come from a source or area which contains corrosive or other
contaminants as outlined in section 9.8.1, especially Table 9.11 and Table 9.12.
The boiler must be positioned and installed by a qualified installer or gas company in accordance with all applicable
standards, local codes and regulations. Commissioning of the boiler must be done by a qualified installer or
technician, who has been trained for this type of boiler.
In the Commonwealth of Massachusetts this boiler must be installed by a licensed Plumber or Gas Fitter.
The installation area/room must have the following provisions:
• 120 V - 60 Hz power source socket with ground.
• Open connection to the sewer system for draining condensing water.
• A wall or stand to properly support the weight of the boiler.
• Depending on the current of the used circulator, apply a circuit break er betw e en 6 and 12 amps
local authority. Where required by the authority having jurisdiction, the installation must conform
to the standard for Controls and Safety Devices for Automatically Fired Boilers ANSI/ASME
fittings, and the we ight of the w ater. If not, it is r ec ommend ed to mount t he boi ler by means of
