16 SAVIO HEAT ONLY MANUAL
Venting 9.
The SAVIO is a mechanical draft, side wall vented boiler. There are two ue options available
- separate and coaxial. The coaxial option has one con guration shown on the next page. The
separate option has two possible con gurations shown on the following pages.
Restrictor Sizing 9.1 :
Each exhaust option is shipped standard with 3 feet of exhaust pipe, 3 feet of intake air pipe .
There is also a restrictor kit in which there are some restrictors that must be placed in exhaust
breech of fan on the top of the boiler (Fig. 9.1) according to the ue con guration used.
If additional ue piping is need for a particular application, it can be ordered separately in 3 feet
increments. Depending on the nal ue pipe length, an alternative restrictor may be required.
Refer to the tables 9.1 for proper restrictor ring sizing

Table 9.1
Fitting the flue system: 9.2
In general, it has to be taken in consideration that the horizontal sections of the flue
pipe must have an horizontal sloping not less than 1.5 degree (0.3 in per ft) away from the
boiler.
In the standard horizontal ue kit the ue pipe is angled within the air duct therefore the air duct
must be horizontally installed.
If one or more exstensions have to be used they must be adequately supported so that there
is no sag in the ue pipe and a minimum fall of 1.5 degree (0.3 in per ft) over the whole lenght
towards the boiler is ensured.
