Gas Fired - Gold design, hot water boiler stopped working as a result of Pressure Switch not actuating to enable current flow for flame ignition.
This unit is an older version - lacking the Condensate Tank!
Checked the two tubes to Gas/Air Manifold for leaks. (Able to actuate the Pressure Switch by blowing in the tubes.
Replaced the Pressure Switch with no success.
Checked for clear air intake and exhaust, and ensured clear holes in the blower assembly.
