Fire or Explosion Hazard.
Can cause property damage, severe injury, 
or death.
Follow these warnings exactly:

1. Plan the installation as outlined below.
2. Plan for frequent maintenance as described in 

the Maintenance section.

a

Flange kits include one flange, one O-ring and four 
mounting screws.

b

Do not use flanges on control models with 3/4 in. inlet 
and 3/4 in. outlet. On models with 1/2 in. inlet and 
3/4 in. outlet, use flanges only on the 1/2 in. inlet side.

Heavy demands are made on the controls when 
intermittent pilot systems are used on central heating 
equipment in barns, greenhouses, and commercial 
properties and on heating appliances such as 
commercial cookers, agricultural equipment, industrial 
heating equipment and pool heaters. 

Special steps may be required to prevent nuisance 
shutdowns and control failure due to frequent cycling, 
severe environmental conditions related to moisture, 
corrosive chemicals, dust or excessive heat. These 
applications require Honeywell Home and Building 
Control Engineering review; contact your Honeywell 
Sales Representative for assistance.

Review the following conditions that can apply to your 
specific installation and follow the precautions 
suggested.

This control is designed for use on appliances that 
typically cycle three to four times an hour only during the 
heating season. In year-around applications with greater 
cycling rates, the control can wear out more quickly. 
Perform a monthly checkout.

If a control gets wet, replace it. If the appliance is likely to 
be cleaned with water or steam, protect (cover) the 
control and wiring from water or steam flow. Mount the 
control high enough above the bottom of the cabinet so it 
does not get wet during normal cleaning procedures.

Dripping water can cause the control to fail. Never install 
an appliance where water can drip on the control. In 
addition, high ambient humidity can cause the control to 
corrode and fail. If the appliance is in a humid 
atmosphere, make sure air circulation around the control 
is adequate to prevent condensation. Also, regularly 
check out the system.
