No the cover would stay on during heating.
IS THERE A PILOT LIGHT THAT STAYS ON, OR BDOES IT GO ON AS NEEDED? IS THIS MODEL WEATHER PROOF?
This heater uses a direct spark ignition meaning that the pilot is only lit while the heater is in use and does not use the older standing pilot light where the pilot is always on. Yes this heater is weatherproof.
I want to install the Hayward Lownox heater on my pool but I live in the mountains at 3,000 foot elevation; do I need to buy a special high elevation heater?
Hello George, The Hayward Universal Low Nox are self adjusting up to 10,000 feet of elevation. Any installation above 2,000 feet will require a special restriction plate to be installed. Luckily, that plate comes standard with every heater so no need to purchase it separately.
Heater model # H400FDN, can be used on pools of all different sizes? The larger the BTU's the quicker the pool will get warm
The required size of a heater depends on the size of your pool or spa and how fast you want to heat up your pool. In the northern states you will probably want the larger heaters to compensate for the colder temperatures. Above ground pools use heaters from 55K to 130K BTUs. In ground pools and spa general run from 100K to 400K BTU. For an average 15' x 30' pool (15,000 gallons), a 300K BTU heater would raise your pool temperature 2 degrees per hour; a 400K BTU heater, 2.7 degrees per hour. For a 20' x 30' pool (20,000 gallons) the temperature rise for 300K and 400K heaters would be 1.5 and 2 degrees respectively. By contrast these same heaters would raise the temperature of an average size spa 30 degrees in 35 and 20 minutes respectively.
Where can my heater be installed?
There are specific venting requirements and clearance distances that must be met to ensure proper operation. Consult the owner’s manual for exact specifications for your model of heater.NOTE: Gas fired heaters should be diagnosed and repaired by trained personnel.
Is a vent required for typical outside installation for the Hayward 150k Ng Lo Nox heater?
For the Hayward Lo Nox heater, you would not need to purchase an additional vent if you are using it outside. If you are installing the heater outside, we recommend you purchasing a heater cover. This will protect your heater from debris, rain, snow, heat- or pretty much anything that could get caught in your heater. The Weather-Out Pool Heater Cover can be viewed on our website.
What is the elevation rating for the Hayward H-Series Low Nox Heaters
Per Hayward, the Hayward H-Series Low Nox Heaters have an elevation rating up to 7,700'
Will a gas heater operate at the low speed of a dual speed motor?
Probably not - Most gas heater will shut off at low GPM levels (20-40) to keep the heater cores from overheating - 20 for 200 BTUs, 40 for 400 BTUs. Depending on your pool system you might get these GPM levels at the low speed but generally these heaters must be run at the motor's high speed.
