Please keep this manual for future reference.

WARNING! There is water contained in the coils of your water heater at all times. If your
water heater is exposed to freezing temperatures, the water in the coils could freeze,
causinga break in the heat exchangerof theunit, or thesupply and returnlines.This kind of
damage will result in water running freely into the space where the water heater is located,
with can cause flooding. DO NOT install this water heater where it may be subjected to a
freeze. If your water heater is in an area where freezing is a possibility, you must turn off the
waterto the heaterand drainit of any waterby using thevalve stemat thebottom ofthe unit
and disconnecting the warm water line. Leave the valve stem and the warm water line
disconnecteduntilyouintendtousethewaterheater.
The MAREY PORTABLE liquid propane gas water heater is capable of supplying
1.5 GPM (gallons per minute) – 5 (LPM liters per minute). This unit has a standard
½”NPTpipefittingsandanadapterforusingastandardgardenhoseforinletwater
supply.
Ignition is automatic and powered by 2 “D” cell batteries (not included). Burners

For a gas supply a standard 20 pound-propane cylinder (not included) is required.
This is similar to the gas tanks used with outdoor grills.A regulator with a hose is
availablewiththeheater.
An additional safety feature is an automatic 20 minutes shut off timer that is reset

Caution: if you detect a possible case of gas leak, contact your local gas supplier.
There may be some conditions which can diminish the intensity of the smell,
makingitdifficulttoidentifyagasleak.
-Outdooruseonly.
-Liquid Propane Gas is denser than air and tends to condense first on lower areas
makingitdifficulttodetectatnoselevel.
-Beforeattemptingtostarttheunit,useasoapyproducttocheckallgasfittingsand
connections.Anybubblingataconnectionindicatesagasleakthatmustbefixed.
- Installing gas detectors is highly recommended for both Liquid Propane and
Naturalgasapplications.Please,turntolocallaws,regulationsandmanufacturer's
recommendationsinordertocorrectlyinstallagasdetectorinyourhouse.
-Units usingNaturalgas are differentfromLiquidPropane models.Foryour safety
donotuseNaturalgaswithLiquidPropaneandviceversa.
- You should never attempt to convert the water heater from Natural Gas to Liquid
Propane.
- Do not connect the unit to a fuel type that is not in accordance with the
specificationstoavoidpossiblefire,equipmentdamageorpersonalinjury.
- DO NOT mount the unit onto a combustible surface (including plywood or other
wood or paper products). Drywall, gypsum or other non-combustible surfaces are
acceptable.

1. Check the box for any damage. If damage is caused because of shipment, it
mustbereportedimmediately.
2.Makesureyouhavealltheparts:
a.GasRegulatorandHandShowerNozzlewithON/OFFControl.
b.HardwarePackand½”NPTtoGardenHoseAdapter.
3.Ifyouareusingaregularstandardgardenhose,pleaseu
se the ½” NPT to connect the garden hose adapter included. Please use the
sealing tape (Teflon) on the threads to avoid leaks. Also check if the screen filter
from the water inlet is in its place, make sure it is cleaned from any particles
blocking the water entrance. Having this done, then you are ready to attach the
waterinput/gardenhose.
4. Install the gas supply into the inlet gas pipe. Do not over tighten it since this can
break or crack the inlet pipe.After you tight the inlet pipe, make sure it cannot be
movedsoastoavoidanygasleakormalfunction.
5. Connect the shower nozzle to the water outlet. Make sure you use Teflon and
connectitbyhandpressureonly.
6. Install the two batteries size “D”. The batteries case will show you how to install
thebatteriescorrectly.

BeforegoingtotheHOWTOUSEsection
Attention: make sure there are not flammable materials around, especially
gasoline or other fumes that can ignite. No objects can be placed on the top of the
heater since they can fall or burn. Both the top and the exhaust of the unit will be
hot.
1. Turn on the incoming water supply ensuring that you have an adequate water
pressure,between5-145PSI.
2.Checkthattheshowernozzleisintheoffposition.
3.Openthegasvalveonthecylinderalltheway.
4.Ifagasleakisdetected,turnoffthegasvalveimmediately.
5.Setthewaterregulatorknoballthewaytotheleft.
6.Setthegasregulatorknobonthefrontoftheunittothehalfwaymark.
7.Turntheshowerhead knob tothe“ON”position.
8. You will hear a series of clicks and the burner will ignite. If the burner does not
igniteafter5seconds,turnofftheheaterandreadthe“Troubleshooting”section.
9. To ensure the draining of water after its use, open the drain valve (ribbed
cylindricalstemnexttothewaterinputvalve).
IMPORTANT: Ensure that the drain valve is open and water is drained from the
unitafter each use to avoid internal damage to thewaterregulator,especially if the
outsidetemperatureisaroundorbelow32ºFor0ºC.
The lack of proper drainage in your unit may cause damage to the heater that will
notbemended.Seeourwarrantypolicy.

*Temperature increases listed are based on use of the water heater under optimal
conditionswith anincomingwatertemperature of48ºF. Variable factorssuchas incorrector

The temperature of the incoming water together with the amount of heat applied
areinfluentialinthetemperatureoftheoutgoingwater.
1.Setthegasregulatortolowpositionandthewaterregulatortohighposition.This
isthelowestsettingavailable.
2. To raise the outgoing temperature, turn the gas valve to the right. There will be a
slight delay between increasing the gas supply and the increase in water
temperature. If you want the highest setting available, then turn the gas regulator
allthewaytothemaximum.Adjustslowlyandcheckthetemperaturefrequently.
The water might reach high temperatures which can harm your skin. Make sure
youtestthewaterbeforeusingit.

1.Makesureyouhave newbatteriesinstalledinthecorrectposition. Checkthecap
ofthebatterycaseforinstructionsonhowtheyshouldbeinstalled.
2. Generally, the main reason why most units do not ignite is because there is not
enough water pressure. The unit must have a minimum of 5 PSI (pounds per
squareinch)ofsustainedwaterpressuretoturnon.
3. Verify thatthewater hose isconnected properly. Ifthisis not well-connected,the
unit will not work. Check that the incoming water pipe is on the far right and the
outgoingoneisinthemiddle.
4. During shipping, if a wire had been disconnected, make sure that the gas valve
andtheswitchareshutoff.Thefrontcoverisheldbyfourscrews,twoatthetopand
two at the bottom. The knobs can be pulled off. All the wiring is done by pushing
together plastic connectors and everything becomes visible when the unit is
dismantled.
5. There is the possibility of finding some kind of epoxy or debris within the water
regulator. Check that the water inlet filter screen is clean. To flush the system you
canreverse thehookupby takingthewater inletpipeand hooking itup tothewater
outlet side and back. If the gas cylinder is contaminated by air, turn the unit on and
offseveraltimestopurgetheairfromthegas.
6. Verify that you have your water supply (cold water inlet) and shower handle (water
outlet).
Waterflowsthroughthe unit,butthereisnohotwatercomingout:
1. New batteries may be required for the ignition switch. Verify that the batteries are
aligned in the proper polarity (+/-). Check the battery case for instructions on how to
installthebatteriesproperly.
2.Checkthatthewaterpressureis,atleast,5PSIsustained.
3.EnsurethattheLiquidPropaneregulatoristhreadedallofthe way to the unit and that
youhaveanadequateamountofgasinyourpropanebottle.
4. Verify that you have hooked up both the incoming and outgoing water supply
properly.Theshowerheadshouldbeattachedtotheoutgoingwaterinlet(locatedatthe
center) and the water inlet should be attached to your incoming connection (located at
thefarright).
