So after deciding on a gas heater, I am now in a pickle. I haven't yet purchased the unit, but reading the manual online, it says:
The unit must be 5 feet from the wall of the pool No problem. The unit must not be installed with the top vent within 10 feet below, or to either side of any opening to the building. Big problem.
I haven't confirmed, but am sure that a window is considered an opening. I've walked my yard and even stared at the scale drawing I created for township code purposes and can't figure a good way to do this. My pool is 5 feet from my house and my pump/filter are up against the wall of my home. Options: Read 1 and 2 for what I've considered, or skip to 3 for the real question
1 - move the filter/pump, and install the heater, on the other side of my deck. That would mean a 15 foot run to/from the pool. Probably need to increase to a 2 HP pump, plus the heat loss, due to 30 feet of hose being under the deck, lying on the cool ground, etc. Add to that the noise level for folks sitting on the deck. The only upside to this is that my gas grill should be located there, so the cost of the pipe run will exist if I go with a gas grill anyway.
2 - I could leave the pump/filter where they are and run 10 feet to my heater. Now, to be 5 feet from the pool wall, the heater ends up cutting into my swing-set area and does ruin the flow of the yard, but... Also, they recommend no more than a 5 foot run from the pump/filter to the heater. So now my pump/filter would be cutting into that same swing-set area. My one daughter loves to swing, so...
3 - Here's my real question Can I, or a certified HVAC tech, connect a vent pipe extension to the heater? I could mount the heater directly next to my current pump/filter, then run a vent extension along the house wall, then up the side of the house, right next to my rain gutter, and vent above the roof. This is exactly how our Radon vent is run and it is in fact a rain gutter that was used to accomplish it.
