Intermittent Pilot Combination
Gas Controls
APPLICATION
These intermittent pilot gas controls are used in gas-fired
appliances with up to 415 ft3/hr capacity at 1 in. wc
pressure drop (8.5 m3/hr at 0.25 kPa) on natural gas.
They include safety shutoff, a manual valve, two
automatic operators, a pressure regulator and a pilot
adjustment.
These gas controls are available in a range of valve
capacities, see Table 1. (Table 2 provides gas capacity
conversion factors.) The suffix letter indicates
temperature range and regulator type, see Table 3.
For CE-approved models, the relevant sections of these
instructions and Table 4 are applicable.

b
Capacity is reduced by 5 percent when using an outlet screen.
c
Valves are guaranteed at only 77 percent of the rating.

Minimum regulation for LP gas is 15,000 Btuh.
e
Minimum regulation for LP gas is 40,000 Btuh.
f
Minimum regulation for LP gas is 50,000 Btuh.
Table 2. Gas Capacity Conversion Factor.
CE-Only Models
These gas controls are used in appliances up to 121kW
or 415 kBTUH on natural gas and approved on EN126,
which consists of one automatic safety shutoff valve,
Class B or C, one servo-operated shutoff valve, Class D,
pressure governor, Class C, manually-operated valve,
with or without pilot outlet. Only the A, H and U models
are available CE-approved.
Table 4 shows the additional specifications for the
CE-only models.
