Question

Carbon Monoxide Venting

Our gas furnace (right side pipe) and our gas water heater vent through the side of the garage, and the vent pipes go up through the plastic rain roof so all the exhaust gases (especially any possible carbon monoxide) don't get trapped under the rain roof to go in the house when the door is open... we have a plug in carbon monoxide detector near the gas cooktop in the kitchen, but the two vent pipes from the garage are just common sense to eliminate any problems
.
To hide the pipes I built a red painted 2x4 frame that will, after the weather is warm enough to put a fresh coat of paint on the garage wall, have SMALL hole lattice cut and mounted

    When it is warm enough to paint the garage wall (minimum 60 F) the lattice comes back off... so for right now it was measured twice, cut once, and it is held in place with three spacer brackets at the bottom (so bottom is 1" below the red frame) and wood clamps at the top and one in the center

    oh, that looks good  much better than the venting.

    Wife likes it (the entire project was her idea) so I'm happy

     

    The PVC pipes are white, so I'm going to test a small spot to see if the grey latex house paint will stick... and if it does I will paint the pipes so they blend into the garage wall and become as invisible as possible... if the latex paint doesn't adhere to the PVC at least they are 'mostly' hidden by the small hole lattice

    from a certain angle your frame blocks viewing the venting pipes?

    Standing on the left the center vertical 2x4 will block the upright part of the furnace vent... but the small hole lattice will cover everything... which is what wife wants

    I will do a test and MAY paint the white PVC with the grey house paint so they blend in with the wall and will then be 'mostly' invisible behind the lattice

    our property includes 1+ acres of pacific ocean, so we're overlooking the ocean, but most of the weather proofing here is for rain because our house starts about 40 ft above sea level with ~1/4 acre of beach roses on our hillside blunting ocean spray and there's virtually no surf unless it's wind generated because of the topography of nw washington and the offshore islands.


    Yea, the rain up there is significant. My brother lives in WA, near Gig Harbor. The apartment that we had was separated from the ocean by another row of apartments. It was the wind and salt mist, in the air that really weathered the apartment.
