Introduction

Ordering Fuel

IMPORTANT
If different fuels are used, Viessmann will not assume
any liability for the functioning or service life of the boiler
plant. Refer to the "Warranty" section in the General
Terms and Conditions of Delivery.
- Burn wood pellets only
- Do not use chemicals or fluids to start fire.
- Do not burn any type of waste or garbage.
- Do not burn gasoline, naphtha, engine oil, or other
inappropriate materials.
- Do not use chemicals or fluids to start fire.
What are wood pellets?
Wood pellets are made from 100 percent natural wood
remnants. This raw material is waste matter created by the
wood industry in large volumes through planing or sawing.
Wood remnants are compressed under high pressure and
formed into pellets, i.e. pressed into a cylindrical shape.
The raw material is stored and transported under completely
dry conditions. System users should also ensure completely
dry storage conditions. This is the only way to guarantee
optimum and effective combustion.
Requirement
Diameter
Length
Bulk density in delivered condition
Net calorific value in the delivered condition
Water content in delivered condition
Fines content in the delivered condition
Mechanical strength in the delivered condition
Ash content, free from water
Ash softening temperature
This value is only binding for pellets certified
to CANPlus.
It indicates the temperature at which the
wood ash is deformed and can therefore
cause fusions in the combustion chamber.
Chlorine content, free from water
Sulphur content, free from water
Nitrogen content, free from water
m-% = percentage by mass
Consequence of overstepping particle size:
- Increased maintenance because of a substantially higher risk of malfunction
- Shortened service life of the conveyor augers and drives

Delivery methods
Pellets are sold in sacks, in bulk on pallets and loose.
In their loose form, pellets are transported by silo tanker
and pumped into the storage room via a hose system.
Careful handling of pellets ensures a low proportion of
dust, perfect fuel charging and a constant boiler heating
output.
Note: The pellet vacuum system hopper inside the boiler
has a capacity of approx. 3.5 cu. ft (100 L).
This corresponds to approx. 143 lbs. (65 Kg) of
pellets.
Pellet requirements
It is recommended that the pellets used comply with the
requirements of the Pellet Fuel Institute (PFI - Standard or
PFI - Premium) and/or CANPlus grade A1 and/or CAN/CSA
- ISO 17225 Part 2 Standard.
