6.1.4 Optional Gas
Pressure Safety
Switches
If the manifold is equipped with optional high and/or low gas pressure switches, the
switches protect against an upstream gas control malfunction that would cause an
increase or decrease in the regulated gas pressure.
The low gas pressure switch is an automatic reset switch that is factory set to activate
if the gas pressure is 50% of the minimum as stated on the unit rating plate.
The high gas pressure switch is a manually reset switch that is set to activate if the gas
pressure is 125% of the outlet pressure stated on the rating plate.
6.2 Gas Heat
Section
Condensate
Drain(s)
A Model SHH heat section has a condensate drain connection on the secondary heat
exchanger and a burner condensate drain connection. Models PDH and SDH have a
burner condensate drain connection if ordered with Option CS2.
Follow the requirements in this section that apply to the installation. Connect all required
drain lines and install traps as illustrated. Fill traps with water. Empty the condensate
drains into a sanitary drain system. Drains may be joined downstream from the traps.
Periodic cleaning of the condensate drain pans, traps, and piping is required. If a drain
has a cleanout opening, be sure to close the opening after cleaning.
