2.6 Gas Piping Considerations
Before making the gas hook-up, make sure the boiler is being supplied with the type of fuel shown on
the boiler nameplate.
Supplying a fuel other than that shown on the app
liance’s
nameplate can lead to over firing of the appliance. This can
cause damage to the equipment which could result in serious
injury and/or death.
The boiler shall be installed such that gas ignition system components are protected from water
(dripping, spraying, rain, etc.) during appliance operation and service (circulator replacement, control
adjustment, etc.).
2.7 Water Quality Standard
The P-K SONIC
®
boiler’s heat exchanger is made of stainless steel. The heat exchanger requires
proper water
conditions to remain efficient and function properly. For more information, refer to Harsco
Industrial, Patterson-Kelley
’s Water Quality Standards for Hydronic Boilers in Multi-Metal Systems in
– Water Quality Standards Quality Standards for Hydronic Boilers in Multi-Metal
, as this applies to the warranty of your heat exchanger.
3 Installation
3.1 Overview
For site preparation follow the guidelines established in Section
. Section 3 details the installation
