Marey Power Gas GA5L/10L/16L Tankless Water Heaters at Elevation

The Marey Power Gas naturally drafting gas tankless water heaters model GA5L/GA10L/GA16L are good for up to 6,000 ft elevation.  There are many people running the units at even higher elevations and the units will still operate well.  The air and gas mix at higher elevations will cause sooting in the heater exchanger and flue exhaust so this wants to be checked periodically.  You have to be aware that you will also loose 4% of your heat rise for every 1,000 ft above sea level...  this is applicable to all gas appliances.

Venting Change for Marey Power Gas Models GA5L/10L/16L

GlobalTowne is an authorized distributor of the Marey gas and electric tankless water heaters.  Marey has recently updated their manual for the power gas GA5L/10L and 16L units.  The installation manual has been revised to show that the 5L/10L and 16L power gas units must be vented vertically up through the roof.  The minimum vertical vent height shall be no less than 6'. Sidewall venting on a naturally drafting unit is not permissible and is against the National Fuel Gas Code (NFGC).  Below is a diagram that shows the vertical venting and also the venting specifications for each unit. 

Venting Specifications for:
Marey Power Gas GA5L - Uses 4" diameter double walled galvanized type B-vent

Marey Power Gas GA10L - Uses 4" diameter double walled galvanized type B-vent

Marey Power Gas GA16L - Uses 5" diameter double walled galvanized type B-vent

Marey Gas Tankless Water Heater Deactivation Issue

This is to address the issue of deactivation in the Marey gas tankless water heaters in warmer climate areas such as S. California, Florida, Texas and Arizona.  Deactivation is an issue when the incoming cold water to the Marey gas tankless is warmer than normal and the unit produces hotter water than normal and then when trying to add cold water to regulate the temperature the unit shuts off and "deactivates".  Turning the hot water tap off and then back on would reignite the unit but then the user would be faced with the same situation.  There are a couple options for addressing this.

1.  The user would want to adjust the Marey gas tankless to the "summer" setting which will give the burner it's lowest BTU burn point.

2.  If the user has the unit set to the summer setting and is still experiencing hotter water than normal then they would want to increase flow.  Increasing flow by turning the flow control knob to its max flow will increase flow through the heater keeping the unit active and giving a little cooler water and the end user will not have to add in so much cold water to cool the water down.

For further instructions on how to combat deactivation in warmer climate please call Marey Technical Support at 855-627-3955.

Marey ECO150 Whole House Electric Tankless Water Heater

GlobalTowne is now carrying the Marey electric tankless water heaters. The Marey ECO150 is a 15KW whole-house electric tankless water heater.  It is recommended that you have at least a 150 amp electrical service to your home before installing the Marey ECO 150.

The ECO150 is good for 1 major application (1 shower) at a time in the southern states.  The Marey ECO150 may be too small for the northern states where the incoming ground water is a lot cooler.  Please reference the Temperature map at the bottom to make sure this is the right unit for your area. The ECO150 has a digital display and shows the temp of the hot water when in use.

Marey heating elements are made from a single piece of cast aluminum, so there will never be water leakage non electric leakage in the heating chamber.
