Electric Pool Heaters

Propane Pool Heaters

Hayward H-Series heaters feature a wealth of advances to
deliver precision water temperature control and achieve the ideal
swimming pool and spa comfort level.
The Hayward H-Series heater represents the very latest
in heating technology for swimming pools and spas. Advanced features
include digital LED control panels on all electronic direct spark and
induced draft hot surface heaters, a rust-resistant water path with
polymer header assemblies, and a rapid-heat combustion chamber. H-Series
heaters are easy to install and maintain, thanks to its low profile,
lightweight and CPVC plumbing capabilities.
In addition, all Hayward H-Series heaters are all
equipped with a Cupro Nickel Heat Exchanger for efficient heating and
superior durability. Cupro Nickel provides improved durability and
longevity against the damaging effects of erosion that can occur under
high-flow conditions, corrosion from occasional pool chemical
imbalances, and is ideal for salt-water based pool systems.
For extra protection, the cupro nickel material has been
coupled with an improved flow rate by-pass control. Together, these
added technological improvements ensure that your Hayward heater
outperforms and outlasts expectations.

PLUMBING & WINTERIZING
PLUMBING: The unit has two positions
labeled INLET & OUTLET. These are 1-1/2" schedule 40 PVC Pipe "Glue type
Fittings". Cut into the pool’s return line after it leaves the filter
and run pipe to Inlet position. Then, run pipe from Outlet position back
to remaining segment of pool’s return line.
We recommend that you install on 1-1/2" PVC Tee. If you use a tee in
this position, it will make it easier to winterize the unit. Install a
drain plug in the bottom of each tee & simply remove these plugs to
winterize. (see winterize instructions below) You may experience
back-pressure on your pressure gauge at the filter after installing the
unit. If so, installation of a bypass line and valve will eliminate the
problem. If this is necessary, open the valve just enough to relieve the
back-pressure.
WINTERIZE: Remove drain plugs on bottom of the Tees at the
Inlet and Outlet positions, blow compressed air into the outlet position
tee until all water quits coming out of inlet position tee.
HANDLING/ASSEMBLY/INSTALLING
HANDLING: Always lift the unit from the
bottom. Never try to lift by the top plate. While on the pallet, use a
pallet jack or lift truck to move. After removing from pallet, a two-
wheeler may be used on the side of the unit opposite the manifold cover
box, left side facing the front of the unit.
INSTALLING: Place the unit three feet from existing
buildings or obstructions. Do Not put unit in any enclosure (leave
outside).
ASSEMBLY: Inside the unit, you will find a 24" piece of 6"
stove pipe with crimping on both ends. One end of the pipe has a small
ring at the end of the crimping. Install this end in the stove, put the
cap on the other end and position the temperature indicator
approximately halfway up the pipe.
OPERATION INSTRUCTIONS
1. Make sure your pump is running and is flowing through
the unit, if for any reason the water flow is interrupted (power outage,
etc.) extinguish the fire immediately.
2. Place small kindling in the fire-box, set the material directly on
the fire brick bottom (Don't use a log rack). To ignite, use paper or a
fireplace starter log, never use liquid flammable materials, once the
fire is started, add larger logs and keep the fire box full. When
operating at full capacity, it will be necessary to add wood every two
hours depending on the type of wood used. At night, fill the firebox and
close the draft doors, it will usually only maintain the pool
temperature at night. In the morning, after 8 to IO hours, you should
have a good bed of coals to start the daytime burning procedure again.
3. Draft Control: When first getting the fire started, open draft
control doors completely open. You can even leave the door ajar to get
additional draft, if needed. Leave draft doors open until the
temperature indicator on the chimney reads in the efficient range, at
that point adjust draft control and add wood to keep the temperature in
the efficient range. When operating in the efficient range, you should
get a 3 to 6 degree temperature difference between water going into the
heater versus water returning to the pool.
4. When heating your pool, you should use a solar or thermal blanket to
reduce the loss of heat generated, this is especially important at
night.
