Advise owner to keep direct vent

termination and air intake free of

debris, snow and ice.

NOTE: Surface discoloration on the

outside of the buildin may occur if the

burner is not properly adjusted.

Viessmann will not accept any

responsibility for such discoloration.

NOTE: Direct Vent exhaust system

operates under a positive pressure

developed by the burner. Make sure all

vent connections and observation port

on the boiler are sealed air-ti ht by

ti htenin screws and usin hi h

temperature silicone sealant if

necessary.

NOTE: The vent components must be

supplied without any alteration except

for the len th of the flex pipe to be cut

to the desired len th.

Installation

nstallation of nsulated Stainless Steel Flexible Oil Vent

In addition to the following

instructions, also consult

Field Controls Direct Vent

ystem manual for detailed

instructions on how to install

the venting system.

Use a 4” to 3” reducer (not supplied)

to connect an intake pipe to the Riello

burner.

If no air intake is required a=0 then

provide combustion air supply to

mechanical room where the burner is

installed. The burner requires fresh air

for safe operation and must be installed

in a mechanical room where there are

provisions for adequate combustion

and ventilation air.

Refer to Vitorond 100

Installation and ervice

Instructions.

Avoid dips in the ventin system when

usin the flexible insulated stainless

steel oil vent.

The direct vent kit includes a VRV-4

vacuum relief valve which must be

installed in the air intake pipe as close

as possible to the burner when usin a

Beckett burner (see Fi . 1).

*The direct vent kit includes a

Viessmann-specific stainless steel

boiler-to-vent transition adaptor.

Do not install the regular galvanized

vent pipe adaptor shipped with the

boiler. This galvanized vent pipe

adaptor is intended for chimney venting

application and therefore must be

discarded in a direct vent application.
