I’m installing a 4”...

I’m installing a 4” z vent on my propane on demand water heater at camp

Contractor's Assistant: How long have you had your 4”?

I’m installing a 4” z vent on my propane water heater my question is about the backkflow preventor. The arrows show the direction of flow but when I install this way the damper stays shut is this correct

Contractor's Assistant: What have you tried so far?

Haven’t tried anything just want to make sure my installation is proper

Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

I can't answer model specific questions without knowing the brand and model of your unit. Generally the damper is closed except when the burner is firing. You always install with the arrows in direction of flow.

My heater is a Marey 10L indoor water heater. Propane with D cell batteries for ignition. But I think you have answered my question just wanted to be sure the arrows were right for flow

Do you have more questions? If not I'd appreciate a favorable rating. This thread won't go away and I'll answer related follow up questions even after you rate me favorably
