WHATCHLORINE
DOES
Two pool guests
you do not want arealgaeand bacteria.
Toget ridot themand make poolwater
sanitary
tor swim'
ming - as well as to improvethe water'staste,odor and
clarity- somesort of diainfectenl
must beused.
Chlorine,
universally
approvedbyhealthauthorities,
isthe
accepteddisinfecting
agent
forbacteria. And,by
maintain'
ing a freechlorine
residualor no lessthan 0.6
ppm(parts
permillion),algae
can also be prevented.
WHATISCHLORINE
RESIDUAL?
Whenyou addchlorineto the pool water,a portion
of the
chlorine will be consumed in the process ol deslroying
bacteria, algae and othet oxidizable materials. The
chlorine remaining is called chloline residual.
You can
determinethe chlorine
residualot yourpool waterwith a
reliabletest kit,available
lrom yourGuardex
dealer.
Youmusl mainlain

residual
leveladequale
enough
to assute
a continuous
kill ot bacteria
or virusin-
troduced into pool water by swimmers,
through the air,
fromdust,
rainorother
sources.Since
chlorine
residual
is
lowered by sunlight (ils ultraviolet rays decompose
chlorine)
it is impossible
to mainlain a constant residual
tevelwith most torms of chlorine unless a mechanical
device
- a Hypochlorinator
- is usedto feed the chlorine
compound
coniinuouslY.
Whetheror not you havesuch a
device,it is wise to test
pool water regularly, never
allowing chlorine residualto

CONNECTIONS
GAS
LINE
Before
installingthe
gas
line,besure
to check
what
gas
the heaterhas beendesigned
lo burn.
This is important
becausedilterenl typesof gas require
differentgas pipe
sizes.
The rating plate on the heaterwill indicatewhich
gas the heater is designed to burn.
The
lollowingtable
shows
whatsize
pipeis requiredforthedistance
from
gas
meter to the heater.The table is for natural gas at a
specific gravity
of .65and propane
at specific gravity
of
1.5.
When sizing
gas lines,calculate 3 additional
feet of
siraight pipefor every
elbowused.
Thepipesizes
shownin this tablearefor natural
gas For
propane
gas,
decrease
bYone size.
When
layingthe
gasline,avoid
getling
dirt,
grease
orother
foreignmaterial
in the pipeas this maycausedamage
to
the
gas
valve,
resulting
in heater
failure.
The
gasmetershould
bechecked
to makesurethat it will
supply
enough
gaslo theheater andanyother
applaances
that may be usedon the same melel.
The
gas
linelromthe
meter
willusuallybeof a larger
size
than the gas valvesuppliedwith the heater'
Thereforea
reduction of the gas line will be necessary Make this
reduclion
as closeto the heateras possible.
Theheaterandanyother

The heaterand its gas connections
