and this means that you simply can’ t forget them opened. An on/off switch is
always present together with a pressure switch, a gas valve and different high
limit switches in safety circuitry, based on model and size. Keep in mind that
you will need to properly install and vent gas pool heaters and the linked
plumbing so that hazards will never appear.
There are some problems that can appear with gas pool heater plumbing
but most of them are easy to solve in most cases. The most common one stands
in the fact that the pilot would not light. In most cases we are dealing with low
gas pressure, improper venting or an inadequate air supply. You will need to
make sure that the gas is turned on and if you use propane make sure that the
tank is filled. The water run-off on roofs or sprinklers must also be checked
while also making sure that there are no clogs in the gas pool heater
plumbing
system. Another problem might be that the water will not reach the needed
temperature. In this case you might have the thermostat set too low.
Also, if there is heat loss greater than heat input you can get the same
problem. This happens when the outside temperature is just too low, the heater
does not have a proper gas supply or it might just be too small. A solar cover
can be installed to slow heat loss and if you have a faulty high limit switch you
should shut off the heater or more problems can appear. If you see that the
heater cycle goes off before the desired temperature is reached the water flow
might not be adequate, because of a closed valve, dirty filter, reversed water
connections, faulty pressure switch or an external bypass. The thermostat must
also be checked for possible faulty calibration.
Using solder fittings with plumbing copper pipes
In order to perform this action you will need thin gauge solder, plumbing
solder flux and wire wool as materials together with a blow torch, a damp cloth
and a heat screen. The first step is cutting all pieces of pipe to the proper length
and cleaning every end of them with using a piece of steel wool. Every piece of
pipe needs to be slid into the connector while making sure that they go in until
reaching the stop in the body. A bind pipe means that there is a distorted end to
the pipe (which means you should cut another length of copper pipe), a burr is
found on the outside of the pipe (you will need to remove it) or there is an ob-
struction present in the body (you might need to get rid of the connector or you
might use a round file to remove the obstruction if it is found off the solder
